I am using AdMob in an iOS game and I recently updated it to include the AdMob SKAdNetworkIdentifier in my Info.plist file (because there was a warning in my AdMob account to do so). Google's identifier is:
cstr6suwn9.skadnetwork
This all seemed to work fine and the warning on my AbMob account page disappeared.
But then a few weeks later I got another warning and when I check this page:
https://developers.google.com/admob/ios/ios14
it says there are a 32 more SKAdNetworkIdentiers in the "select additional buyers" section which AdMob suggests we also have to include.
I have not updated my game yet and the warning has disappeared anyway, so I don't know wether to add all these extra identifiers or not. It looks like the list is regularly added to (last updated 9 April), so seems a pain to have to keep updating my app with them if that is Google's plan.
I don't use "Mediation". So do I need all these 3rd party ones or just the Google one?
