I have enabled developer mode in flutter app development. I am using Firebase Cloud Messaging to send notifications. everything works fine There is a notification coming to the normal app. But after a while I can no longer send notifications to the app.
{"multicast_id":5417898622260949101,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}
The fcm device token doesn't seem to work. This caused me to request a new fcm device token. and after using it for a while, it came back like the first time
Is this caused by the APN token being canceled? or caused by enabling developer mode to develop apps.
