When I test run my game on an amazon fire tablet with admob test device configured, the test ads load fine. But when test devices aren't configured the ads fail to load, and the log reports include
...onAdFailedToLoad: Internal error ...
... Ad failed to load : 0 ...
...' requires the Google Play Store, but it is missing.'...
Applovin (within my admob mediation) also reports 'Could not collect Google Advertising ID ...'.
Game is listed on Play Store, not yet added to Amazon Appstore.
on Fire tablets, are the play services for admob ads not pulled in via gradle dependencies? (com.google.android.gms:play-services-ads:20.5.0 and/or com.google.android.gms-services-ads-identifier:18.0.1)?
Would these issues resolve themselves once game is listed on Amazon Appstore & after I indicate it's listing in Admob->App settings-> App stores ? would a GAID only exist if a kindle device had play services side loaded? And if not, only non-personalized ads?
I appreciate any info
