Ok, I think I've fixed it.

These are the change make iOS release mode work again:

1. Info.plist

    <key>FirebaseAppDelegateProxyEnabled</key>
    <false/>

Change to

    <key>FirebaseAppDelegateProxyEnabled</key>
    <string>NO</string>

2. pubspec.yaml

firebase_messaging: ^6.0.16

Change to

firebase_messaging: 6.0.15

These change are against official document but I don't know why it work but hey it work!

it works for my

[sam0829]

This is real! Push notification works fine in debug mode but doesn't work if the app is in release mode. I get the same InvalidRegistration error when I send notification on token received in release mode. However, it works just fine for the token received in debug mode. I am using firebase_messaging: ^7.0.0

[maksym-ostrovyj-ew]

Try to add application.registerForRemoteNotifications() in your AppDelegate.swift. It worked for me. ver 7.0.0

[rimidalv]

Try to add application.registerForRemoteNotifications() in your AppDelegate.swift. It worked for me. ver 7.0.0

It doesn't work for me. ver 7.0.3

[devmoonho]

This definitely worked for me.

 <key>FirebaseAppDelegateProxyEnabled</key>
 <string>0</string>

[kunkaamd]

This definitely worked for me.

 <key>FirebaseAppDelegateProxyEnabled</key>
 <string>0</string>

it doesn't work for me ver 7.0.3, in ios 13.7. onMessage did not call with release mode. Have any other solution?

[kunkaamd]

I have fixed that by using APNs key. maybe I have a mistake in config production APNs Certificates.

[Andrew-Tolentino]

This worked for me when running on iOS14 and Xcode 12.1 on release/profile mode. Prior, it was only working in debug mode on my device. As mentioned in previous comments, I did the following....
1. Switched my firebase_messaging package from 7.0.3 to 7.0.0
2. I then changed this in my Info.plist -
<key>FirebaseAppDelegateProxyEnabled</key> <false/> to <key>FirebaseAppDelegateProxyEnabled</key> <string>0</string>

Hopefully this helps!

I tried this @Andrew-Tolentino. Didn't work.
If I donot change my info.plist I get the notification when the app is closed but not when it's open. I check it by adding a toast in onMessage and onResume.
If I add this in my info.plist I donot get notifications at all.

But everything works fine on emulator or on physical device in debug mode. when I create a build for development and distribution it doesn't work.
