The issue you are facing:
I do not receive any notofications on two different iphones. The latest talk app is installed and everything is running smoothly, but no notifications are sent either invations for calls nor messages.
I do get notifications though in th web gui.
Any help to debug this issue is highly appreciated.
are you using the iOS app from the App Store or are you building your own one?
If you are using the one from the App Store, you should be able to receive push notifications.
If that’s your case, could you try to log-out, remove the app and reinstall it again?
