After transferring of app, all push tokens in FCM are invalid and users have to reinstall app in order for push to work

[JakobMaaloe]

[REQUIRED] Step 2: Describe your environment
IOS app & Firebase Console

[REQUIRED] Step 3: Describe the problem

We are facing the same problem as described in issue 2125

We have just tried the following:

1. Reinstall the app on a device
2. Push message from our server to the FCM token -> The user receives the message
3. Change APN auth key to an old one
4. Change APN auth key back to the new one
5. Delete the FCM token on our server
6. App requests new FCM token on startup and receives the same FCM token as before it was deleted
7. Push message from our server to the FCM token -> The user doesn't receive the message

We have transferred the IOS app to a new account and now we can only push to our IOS users after the remove and install the app again.

Please, any advice on what to do will be greatly appreciated! Having to communicate to ALL IOS users that they have to reinstall their app is devastating!

Thanks in advance!

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hey @JakobMaaloe, please file this here so we can look at your Firebase project and instance IDs.

Hi Morganchen12.

Support case has been created with the APNs (from apple console - I hope this can be used)

We've just tried the following:

1. Reinstall the app on a device
2. Push message from our server to the FCM token -> The user receives the message
3. Change APN auth key to an old one
4. Change APN auth key back to the new one
5. Delete the FCM token on our server
6. App requests new FCM token on startup and receives the same FCM token as before it was deleted
7. Push message from our server to the FCM token -> The user doesn't receive the message
   One solution could be if we could force all users FCM token to refresh... Any way that's possible?
   I can send you the APNS token from Apple console in a support ticket if you still need it.

We cannot update the production app with new sourcecode unfortunately.

Thanks!

Hi @morganchen12 ,

Any news on this?

Our users don't get push messages so it's vital for us to find a solution asap...

Hi @JakobMaaloe, the Firebase support team doesn't work on weekends. Normally, when the APNs key is changed or invalidated, the tokens on the client should invalidate and reset over a short period of time. The clients should then regenerate new tokens that work when sending notifications. We're looking into why this isn't happening as expected.

[JakobMaaloe]

Ok, thank you for the update. Fingers crossed that the invalidation can happen soon.

Hi Jakob, please respond to the support email:

Could you also share the debug logs when you switch Apple accounts on the console and Xcode certificates at the first time the app is re-opened after these APNs changes (and APNs token change) has occurred?

Hi Morgan Chen, Thx for getting back to me! Unfortunately I'm not experienced in the Apple Development / publishing - we have moved to the new account as the dedicated Apple developer exited from the company. How do I retrieve the debug logs and do you mean from within the app on the phone, from the Apple console or from xcode? Same question goes for the certificates. In the meantime, could you invalidate the FCM tokens that haven't been invalidated during the so our users have push messages working again? Thanks. Br.
