I've been breaking my head on this today and yesterday, for some reason my iOS application is not receiving any firebase notifications. For as far as I know I have done everything as it should be.
- I have checked the certifications in my Apple developer account and everything is set up correctly (see screenshots).
- I am testing on a physical device
- Firebase is set up properly and the logs show it connected to firebase correctly
- I have enabled push notifications, background fetch and remote notifications in the capabilities tab of the project
- I have added my APN key from my Apple console to Firebase
When sending a notification through the Firebase console to a topic or to all iOS apps nothing happens. I have the same app running on android smoothly which is receiving all notifications when targeted.

Apple certificates:
Any help would be much appreciated.
FIRInstanceID.instanceID().setAPNSToken(deviceToken as Data, type: FIRInstanceIDAPNSTokenType.sandbox)
so i am usingFIRInstanceIDAPNSTokenType.sandbox
I am using a iOS Development provisioning profile with an iOS Development certificate. – Milan
