Recently, we received an email informing us that our app is impacted by the deprecation of GCM:
Your Firebase project(s) that use Firebase Cloud Messaging APIs are listed below:
App-Name(XXXXXX)
Your recent usage of impacted APIs/features: GCM SDK
However, we have long migrated from GCM to FCM. In fact, the latest FCM SDK version that our app uses in production is 23.0.0. I have also verified that our app dependencies do not utilize GCM.
I'd like to ask why our app has been flagged even though we have already migrated from GCM to FCM? Any help will be appreciated.
Thank you!
I contacted Firebase and they said that if we're using FCM in our apps, we can ignore the notice. The alert might be for outlier user with an old app version. Since we've already switched to FCM a while back, our setup should be fine.
