[Bug]: "notifications turned off" modal appears immediately after accepting notifications (iOS)

[molesquirrel]

What happened?

Multiple users have experienced this: on initial prompt for notification permission, the user taps Allow. Immediately, the panel which states "Open Settings" - "You currently have notifications turned off for this application. You can open Settings to re-enable them" appears.

Going into settings, notifications have successfully enabled for the app.

The code has not been altered in months (prior to the issue), but these reports have cropped up in the last 2-3 weeks.

Flutter code:

 OneSignal.initialize("606dfb59-c107-4a56-968b-3ba657177a16");

 /* other app initialization code */
 bool accepted = await OneSignal.Notifications.requestPermission(true);

The verbose debug logs are pasted below. Note that while the logs might reference an earlier version of the OS SDK, I am currently testing 5.3.2 with no change in behavior.

All potential PII info (app id, token id, sub id) has been replaced in the log.

I am happy to provide any other information required.

Steps to reproduce?

1. Version 5.3.2 installed.
2. iOS user (version 18.5, at least) opens app.
3. After user login, the app calls the above Flutter code to request permission.
4. User accepts
5. Immediately, panel suggesting that the user did not accept appears.
6. User can confirm in iOS settings that the notifications are allowed.

What did you expect to happen?

The second modal should not appear.

OneSignal Flutter SDK version

3.5.2

Which platform(s) are affected?

• iOS
• Android
