Unity: AdMob Mediation failing to let sources bid

[Frank van Hoof]

I've implemented AdMob Mediation with 5 different sources in a Unity Application.
The 5 sources:

- AdColony

- AppLovin

- IronSource

- TapJoy

- Unity Ads

However, ads are only being served from the AdMob Network.

I'm encountering a myriad of different issues:

- Ad Inspector does not open with Gesture

The ad Inspector does not open when using the gesture, if I'm running a debug-build (i.e. a build that wasn't downloaded from the store)

If I open the Inspector through a Button (programmatically), it opens just fine.

- Only 4 Adapters show up in the Init

I print the Adapters that are loaded in the MobileAds.Initialize()-call
The results I get are:
- com.google.android.gms.ads.MobileAds - Ready
- com.google.ads.mediation.applovin.AppLovingMediationAdapter - Ready
- com.google.ads.mediation.adcolony.AdColonyMediationAdapter - Ready

- com.google.ads.mediation.unity.UnityMediationAdapter - Ready

TapJoy & IronSource adapters are not showing up at all!

- Only 3 Adapters show up in the Ad Inspector
When checking the Ad Inspector, the following 3 adapters show up:
AppLovin (v11.4.300)
AdColony (v4.8.0)

Unity Ads (v4.2.101)

All of these are Found & Initialized. The other adapters (TapJoy & IronSource) don't show up here either

- No Bids from any Mediation Adapters

Only bids from the AdMob Network are showing up on my AdPlacements. No other Adapters show up. If I manually pick a single ad source for testing, it doesn't fill, and throws a 'no ad config'-error.

- Opening the Mediation Test Suite crashes the app

If I try to open the Mediation Test Suite, the entire app crashes (to 'desktop').

Versions & Tools:

- Unity 2021.3.2f1
- AdMob 7.1.1
- Mediator-Versions (see above)

- OS: Android 10 (Oppo ColoOS V7.1)

- Registered as Test-Device? Yes
- AdMob Mediation Test Suite: Latest as of writing ( https://dl.google.com/googleadmobadssdk/GoogleMobileAdsMediationTestSuite.unitypackage )

Can anybody help me figure out why my Mediation isn't working? It's costing me potential revenue

Minor update:
I was able to get the Mediation Test Suite running by enabling the "Custom Gradle Properties Template" under Publishing Settings
In the Test Suite, the 4 available adapters show up. All have SDK, Manifast & Adapter set to 'Ready' by default, but all have 'Ad Load' set to 'Warning' until I manually try to load an Ad in the Suite

When I do load an ad in the suite, half of them work, and the other half don't:
- AdColony & AdMob work & show a test-ad
- Unity Ads & AppLoving return 'No fill'
