I am using the Parse demo app (ParseStarterProject) and Firebase demo app (Messaging Example) Both using the same Bundle Identifier and GoogleService-Info.plist
I checked first that they were receiving pushes , installing them separately one at a time and using postman to send them messages Then I freshly installed the Parse Demo app and subscribe to a channel Once I received a push notification from parse I install the Firebase demo app (Messaging Example) and subscribe to a topic
FIRMessaging registration is not ready with auth credentials 2016-12-13 19:42:25.648: Failed to subscribe to topic Error Domain=com.google.fcm Code=501 "(null)"
+-70% of the time the app fails to get the firebase push after the migration
Any info on solving this issue will be greatly appreciated
