I'm using FCM service provided by firebase to send push notifications to clients.
But I'm facing a trouble.
I transferred my app to a certain company and made a certificate, which type is "Apple Push Services", recreated using a new CSR of that company.
And I created new .cer file and .p12 file on developer console "Certificates, Identifiers & Profiles".
Then I uploaded the .p12 file onto firebase.
After those settings, I faced the problem; any notifications to ios client don't reach all clients.
Testing by a few iPhones, I found that push notifications got to reach normally after reinstalling the app from app store.
I've never heard reinstalling the app to get notifications, so that I think I might be making some mistakes.
Any hints to solve this problem or anyone has experienced this problem?
Do you have any solution? We are in the same situation.
Can you provide more information on what you mean by "transferred" your application?
Was the application existing in App Store Connect and then you transferred ownership to a different organizational developer account?
Thanks in advance!
