Andy I wish I had better ways to debug in FF. If you know of a way to check to see if functions are call and check logs from the app, please share them here.

Here's some additional information. In my cloud functions log for addFcmToken, I only see entries for managing the function, but no calls to the function. I did see a setIamPolicy permissions error:

\"Permission 'cloudfunctions.functions.setIamPolicy' denied on resource 'projects/mosquitomax-364012/locations/us-central1/functions/addFcmToken' (or resource may not exist).\"

In the video https://www.youtube.com/watch?v=Rg2KlQkJgfM at about 1:45, he mentions additional permissions needed by the flutterflow user in GCP. I added those permissions, then manually deleted the function in google cloud console and then triggered a new deployment from the flutterflow console.

This time when I deployed the notifications functions, the setIamPolicy succeeded. I then deleted the app from my Android phone and added it again, which prompted me to allow notifications. I then saw the fcm_tokens collection and the token for my device was there.

I then sent a manual notification from FF and it worked. Hopefully this helps everyone else facing this problem. The additional roles should be added to the notification instructions.
