Request: update docs about Meta/Facebook ad-network source for Admob mediation: GDPR, CCPA and ad formats

[Liran Barsisa]

I use Admob with mediation for Android apps, and I also use UMP SDK by Google:
https://developers.google.com/admob/android/privacy

I want to add Facebook/Meta as an ad-source for Admob mediation

I've noticed there are no explanation of code for Facebook/Meta about GDPR and CCPA:

https://developers.google.com/admob/android/mediation/meta#eu_consent_and_gdpr

Here are my requests for the documentation of Admob mediation of Facebook/Meta:

1. The only thing I've found was on Facebook/Meta website, but even then it seems it's only for CCPA, and not clear enough:
https://developers.facebook.com/docs/marketing-api/overview/data-processing-options#data-processing-options-for-us-users

I think that if data-sharing/selling is ok, I need to use :

FacebookSdk.setDataProcessingOptions(new String[] {})

, and if the user chose not to allow it, to use :

FacebookSdk.setDataProcessingOptions(new String[] {"LDU"}, 0, 0)

Is this correct?
Please update the docs about it.

2. About GDPR, I've read on some reddit and StackOverflow questions, they work differently, by checking how it is on Facebook app that's installed on the device.
Is it true?

3. I wanted to add rewarded ads like on the docs, but for some reason I don't see such a thing being an option. This is what I see when I try to create a new placement:

It's weird because even Facebook/Meta docs mention it:
https://developers.facebook.com/docs/audience-network/bidding/partner-mediation/admob#google---meta-format-mapping

How come? Please update the docs about how to add each ad-format, including rewarded ads.

4. I've noticed this note on Admob's website for banner ads:
"Note: Meta Audience Network's Banner format supports the medium rectangle display format and flexible width banners with heights of 50, 90, or 250."

First, it shouldn't be "90", because "LARGE_BANNER" is of size 100 (here), and it's even mentioned on Facebook website, so this should be fixed.

Second, it doesn't mention what would happen if we request MEDIUM_RECTANGLE size for banner ad of Facebook or any one that isn't mentioned there. Would it use Adaptive Banner automatically, or always fail? I wonder how it works on other ad-networks too.

Another thing I've noticed that should be updated (sadly I can't edit the original post):

5. About this:
https://developers.google.com/admob/android/mediation/meta#caching_on_android_9

it sends me to this link, which is empty of any useful content:
