FCM tokens are not being generated

Troubleshooting

FF is not generating an FCM token when a user creates an account. Although notifications have deployed successfully (I have verified this because they appear on my firebase database), users do not receive notifications via manual notifications in flutterflow or when I use a "trigger notification action". There also is no subcollection with fcm tokens in my user's collection.

However, when I go directly into firebase and send notifications this way the notifications are received by all users. I would like notifications to be generated with the trigger action from within the app as well.

What have you tried so far?

I have reviewed all flutterflow documentation and retraced my set up steps just in case I missed a step. I've also reviewed other postings in FF community and tried their suggestions.

I've tried deleting functions and redeploying. Relaxing firebase rules.

Did you check FlutterFlow's Documentation for this topic?
