I recently transferred my iOS app from one developer account to another and now I am not able to send push notifications from Firebase Cloud Messaging to my app. I have tried the following:
- Updating the Team ID in the Firebase Console
- Generating a new APNs Key and uploading to the Firebase Console
- Re-configuring APNs on Apple Developer App ID page for the app of interest
a) Generating a Certificate Signing Request on my local machine
b) Uploading this Certificate to the App ID to configure APNs
c) Generating a new certificate based off of this CSR
d) Downloading this new certificate and saving in keychain - Trying to send push notifications from the Firebase Console
It is clear that the FCM Tokens are updated and that the problem lies within something that I am missing / forgetting to do on the Apple side to allow FCM to talk to APNs, but I cannot figure out what I am doing wrong. Any thoughts?
