Notification permission is not shown when app is reinstalled (iOS)

[kanclalg]

Notification permission prompt is only shown once on a device per app. When I delete the app and install again notification prompt is not shown and notification settings are not available in app settings though request returns authorized. Tried to create multiple test apps - all resulted the same.

iOS 15.4

@kanclalg not sure what s happening but it seems impossible. If you delete the app all permissions are lost. I cant tell you much more than this. You need to debug this and see what s really going on. But the theory is that it is impossible!

[kanclalg]

@farfromrefug let's not go to possible, not possible conclusions before actually trying to reproduce it.

I've debugged it to this line https://github.com/nativescript-community/perms/blob/master/src/permissions.ios.ts#L419 It returns true here for isEnabled

Tested again on a new app: it went straight to that line and returned true. No prompt was shown at any time this time.

Test app: TestNotification.zip

I'm using https://www.npmjs.com/package/@nativescript/local-notifications now for requesting permission. It works fine.

@kanclalg OK but then it is not the issue you mentioned before? it never prompts? even on first run ? what I said was impossible was if it worked once but then kept returning true after re installation

[kanclalg]

It might have been some clash with other libs before, I'm not sure now really. Let's stick for now that it always returns true.

@kanclalg thanks for reporting this. Could you try 2.2.8 ?

[kanclalg]

still nothing. Getting [undetermined, true] now.

@kanclalg could you try with @nativescript/ios versin 6.5.5 (clean your platforms dir). I suspect a crash in the v8 runtime (which i dont use)

[NathanWalker]

@kanclalg it's not a v8 issue at all. The result is processed on background thread:

Main Thread Checker: UI API called on a background thread: -[UIApplication registerForRemoteNotifications]

I can help make adjustment. Keep in mind 6.5.5 is JSC runtime and it cheated on several things which lead to misunderstandings in how platform interaction should work.

[farfromrefug]

@kanclalg please try latest version
