iOS push notifications iOS15 & iOS17

[John van de Waeter 4]

Hi All,

Suddenly something weird... push notifications arrive perfectly on iOS 15 devices, but NOT on iOS 16,17 devices.
Same app, D12.1, XCode 15.3, iPhoneOS17.4.SDK

Tested on several iPhones. Delete app, reinstall app, give permission again, it makes no difference.

Google FCM says "InvalidRegistration" when the notification is sent to an iOS 17 device or an iOS 16 device.
iOS 15 (my old iPhone 6s) works okay.

 

Anyone any idea?

 

tnx, John
