[Bug] DeleteTokenAsync receives a new token immediately in iOS

lsw1164 commented 2 years ago

[REQUIRED] Please fill in the following fields:

Unity editor version: 2020.3.23f1
Firebase Unity SDK version: 8.6.2
Source you installed the SDK: Unity Package Manager
Problematic Firebase Component: messaging
Other Firebase Components in use: app, installations
Additional SDKs you are using: none
Platform you are using the Unity editor on: Mac
Platform you are targeting: iOS
Scripting Runtime: IL2CPP

[REQUIRED] Please describe the issue here:

I've tried to handle push notification on/off in iOS. I expected to delete FCM Token to turn push notification off. Even though TokenRegistrationOnInitEnabled value is False, FCM token is received automatically and immediately after DeleteTokenAsync.

Log

FCM: new registration token received
FCM: Retrieve registration token

So. I could not delete FCM Token. It seems like refresh Token, not Delete. After quit my app, Push Notification is still received.

Plz fix the logic where refresh automatically FCM token. On Android, DeleteTokenAsync works well. It does not fetch the new token immediately after DeleteTokenAsync.

Relevant Code:

Here is my code.

// I've put this pair into my Info.plist:
// <key>FirebaseMessagingAutoInitEnabled</key><false/>
// So, 'Firebase.Messaging.FirebaseMessaging.TokenRegistrationOnInitEnabled' is False.

    Firebase.Messaging.FirebaseMessaging.TokenReceived -= OnTokenReceived;
    Firebase.Messaging.FirebaseMessaging.MessageReceived -= OnMessageReceived;
    Firebase.Messaging.FirebaseMessaging.DeleteTokenAsync();

Hi @lsw1164,

Thanks for reporting this issue. I was able to observe this behavior using the quickstart. I'll be discussing this with the team, so I'll be marking this as a bug for now. You may refer to this ticket for updates.

Assign to FCM oncall to take a first look at.

@paulinon can you help to see if this is reproducible?

paulinon commented 2 years ago

Hi @chliangGoogle,

I was able to reproduce this issue even with the latest version of the Unity SDK (8.8.0). After deleting the token, a new one is immediately retrieved.
