Missing Partner Issue in Ad Inspector When Using UMP with AdMob Mediation

[oooOwOooo]

Hi,

I’ve integrated AdMob and UMP into my Unity project to comply with GDPR. In the consent message, I’ve also included all my mediation partners as configured.

However, when testing with the Ad Inspector, I encounter a "Missing Partner" error under the CMP section of the Privacy tab.

Here’s the strange part:

• When consent is given, ads from AdMob and other mediation partners are served, but the mediation partners show up as “Missing” in the CMP section.

• When consent is not given, only AdMob ads appear, but the mediation partners are listed correctly without any "Missing" error.

This issue happens on both Android and iOS.

I’ve confirmed that the mediation partner IDs are included in the AC string, so I’m not sure what’s causing this behavior.

Are there any additional steps I can take to resolve or further investigate this issue?

Thanks in advance for your help.

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

The error message “Missing Ad Partner” is  an ad partner configured in mediation, but not in the TC/AC string. If you've configured an ad partner in mediation, but not in the CMP, the ad inspector warns you of missing ad partners through the Ad partners page. The Ad partners page displays a list of missing ad partners not configured in your CMP and not present in the TC/AC string. When testing, you must consent to all ad partners. For more details, see Adding ad partners to published European regulations messages. 

To learn more about the AC string, see Google's Additional Consent technical specification. For consent details in the TC string, such as the CMP ID and the IAB consented vendor list, click Decode. IAB GPP Encoder / Decoder opens. If you see errors, follow Understand privacy issues. If this does not help, can you please confirm if the reported issue is replicating in our Google Unity samples? If so, kindly share with us the below information privately so that we can check to find the root cause of the issue and may provide the solution:

• app ID and ad unit ID
• Charles logs when the issue reproduced 
• Sample project reproducing the issue

I'm not sure if my previous response was delivered properly, so I'm sending the same message again.

 I have uploaded a sample project at the following link. Please follow the steps below to reproduce the issue:
1.  Connect through a VPN to a European country (EEA). If VPN access is not available, you can click the "EEA" button to open the consent form.
2. On the displayed consent form, choose Consent.
3.  Shake the device to open the Ad Inspector.
4. Use the Ad Inspector to request an ad.
5.  In the requested ad’s privacy signal, the ac field includes values such as 1301, 3234, and 2878. However, in the CMP section of the Ad Inspector, the mediation ad partners are shown as missing.

 Please let me know if any additional information is needed.

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

The Missing Ad Partner warning in Ad Inspector typically indicates that one or more ad partners configured in mediation are not included in the TC or AC string provided by your CMP.

When you've added a mediation partner but haven’t included them in the consent configuration, the Ad Inspector flags them under the Ad Partners tab as missing. To avoid this, ensure that all mediation partners are correctly listed in your CMP and included in the TC/AC string. When testing, you should consent to all partners.

For more information, please refer to:

•  Adding ad partners to published European regulations messages

• Google's Additional Consent technical specification

•  IAB GPP Encoder / Decoder

If errors persist, click Decode in the Ad Inspector to view TC string details, including your CMP ID and the vendor consent list. Also review the Understand privacy issues page for resolution steps.

To help us investigate further, could you please confirm if the issue also occurs with the official Unity samples? If yes, kindly share the following information privately so we can assist further:

• Your App ID and Ad Unit ID
• Charles Proxy logs when the issue occurs

• Sample project reproducing the issue

Hi, did you receive the sample project I uploaded through the survey?
If you didn’t receive the project, please let me know.
If there’s another way to submit it besides the survey, I’m happy to try that as well.
I’m hoping to get this issue sorted out as quickly as possible.

[oooOwOooo]

Hello,

I believe the information I’ve provided so far may have been insufficient, so I’d like to add more details to clearly convey the issue.

My project uses AdMob and UMP, with mediation networks including AppLovin, Meta, UnityAds, IronSource, and LineAds. Adapter initialization is completed successfully. However, when testing under GDPR conditions using a VPN, the following issue occurs:

After submitting consent, the Ad Inspector’s Privacy > CMP tab shows AppLovin, UnityAds, and IronSource as missing. Furthermore, Meta and LineAds do not appear in the list at all. Additionally, when testing each ad network individually, UnityAds and IronSource do not return any ads, which I suspect is due to them being marked as “missing.”

Here’s what I’ve tried so far to resolve the issue:

Checked the GDPR message’s Ad Partner configuration

I selected the default list of ad partners, which includes AppLovin, Meta, UnityAds, and IronSource.

Verified the AC string

  The shared IABTCF_AddtlConsent string is as follows:

2~61.89.122.184.196.230.314.318.442.445.494.550.576.609.1029.1033.1046.1051.1097.1126.1166.1301.1342.1415.1725.1765.1942.1958.1987.2068.2072.2074.2107.2213.2219.2223.2224.2328.2331.2387.2416.2501.2567.2568.2575.2657.2686.2778.2779.2869.2878.2908.2920.2963.3005.3023.3100.3126.3219.3234.3235.3253.3309.3731.6931.8931.13731.15731~dv 
  As you can see, AppLovin (1301), Meta (89), UnityAds (3234), and IronSource (2878) are all included.

Passed consent via code

if (ConsentAccess.IsPartnerConsent("1031")) // AppLovin
{
AppLovin.SetHasUserConsent(true);
CLogger.Debug("[mj] AppLovin gdpr on");
}

if (ConsentAccess.IsPartnerConsent("3234")) // UnityAds
{
UnityAds.SetConsentMetaData("gdpr.consent", true);
CLogger.Error("[mj] UnityAds gdpr on");
}

if (ConsentAccess.IsPartnerConsent("2878")) // IronSource
{
IronSource.SetConsent(true);
CLogger.Error("[mj] IronSource gdpr on");
}

if (ConsentAccess.IsPartnerConsent("89")) // Meta
{
// Meta
CLogger.Error("[mj] Meta gdpr on");
}

I’ve also tried removing the above code, but the issue remains unchanged.

Thank you for your continued support!

Hello there,

Thanks for reaching out.

Instead of connecting to a VPN for testing, have you tried forcing a geography?

Since the ad partners not showing issue only happened when connecting to a VPN, I suspect the device or ad inspector is somehow unable to detect the region change.

Also, would you have a chance to go through our developer documentation on Troubleshoot privacy settings and follow the instructions to resolve the issue?

 

Thanks,

[oooOwOooo]

  The issue persists even when applying Debug Geography instead of using a VPN. Furthermore, the guide you provided does not offer a clear solution other than editing the ad partners in the European regulations, and my project already includes mediation partners in its EU configuration. Is there any other possible solution?

Hello,

Thanks for the information.

To confirm, have you added ad partners to published European regulations messages and implemented privacy settings on the third-party SDKs (see Unity Ads documentation for example)?

In addition, can you export missing ad partners list and provide the app and ad unit IDs for us to debug on our end?

You can reply privately.

Hello there,

Thanks for bumping the thread.

Apologies for the delay; there were U.S. holidays last week.

We are currently looking into this issue on our end.

Would you be able to provide a Charles log that captures all traffic? That will certainly help with our investigation.
