HI @thsbrown

I actually tried our FCM quickstart and did not see the fail. (The pop-up was shown properly as well!)

Note that it is calling FirebaseMessaging.RequestPermissionAsync in the continuation function of Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread

quickstart-unity/messaging/testapp/Assets/Firebase/Sample/Messaging/UIHandler.cs

Line 89 in 72fea4d

Firebase.Messaging.FirebaseMessaging.RequestPermissionAsync().ContinueWithOnMainThread(

Could you check if you configure your Xcode project properly, specifically Capability and Framework part?
https://github.com/firebase/quickstart-unity/tree/master/messaging/testapp#ios

Also make sure that you configure your certs properly.
https://firebase.google.com/docs/cloud-messaging/ios/certs

And do try our quickstart and follow every instructions.

Let us know if this helps!
