My latest app testing results indicate:
Caution: Google Cloud Messaging Detected
GCM is required for Google Analytics. I've previously submitted my app without this issue popping up during the app testing service procedure.
Has anything changed now? I need Google Analytics so I do not want to get rid of it. Google Analytics does not require Play Services either, so I wonder why Amazon is complaining about this now. Moreover, I don't want to create two different APKs for the Play Store and the Amazon Appstore...
