I read in the deprecation notice that expo will continue to use GCM to push notifications to users who have valid GCM tokens. However, I also read in a forum topic that someone said their notifications stopped working after running
expo push:android:upload --api-key <your-token-here>.
We don’t have the new build ready yet with the google-services.json file. Do we wait until that new build is published to upload our new FCM api key? Or can we do it now and expo will intelligently continue to run push through the old method until users start registering with FCM tokens?
