Hello!
We have a problem with getting push notifications in our new app, today it is not in the AppStore, but we are planning to make our first release at the end of this month and we are faced with the problem that push notifications sent from the backend do not reach the application.
The certificate was generated recently, it was checked on the local machine, the certificate is working and the push for a specific token reaches. (testing was carried out using the *.p12 certificate and the program https://github.com/onmyway133/PushNotifications )
The backend sends push messages via the PushSharp library (https://github.com/Redth/PushSharp ) it works on a socket connection with APNS. During the research, we managed to find information that apple has not supported a socket connection since March 31, 2021 (https://developer.apple.com/news/?id=uzyxiriy ). It turns out that we can't send push messages from our backend to a new client application?
If the PushSharp library can no longer send push messages, then the question arises, do we have another application that has been in the apple store for a very long time and still receives push messages using the *.p12 certificate, is there any exception for old customers? This application's certificate was issued this year.
What other reasons could there be that a push message was sent but did not reach the application?
With best regards Eugene!
