Looking at ipsw diffs, guess iOS 26.4 introduced some safety protection that discards notification from untracked APNs token, preventing CloudKit notifications from getting to the app 😂
@khaost how does that turn into third-party applications not syncing for iOS apps? Are the tokens these are using not valid?
@rwitherspoon CloudKit subscription apparently have notification comes in from a special APNs token, that gets dropped by UNC in the previous logic since UNC does not track that token.
@khaost bloody hell, is this why CloudKit notifications of change are not reaching my app on 26.4 test device? I’ve spent a day combing through my code convinced I have a bug. Works for Mac app though, so must be restricted to iOS?
@oberstal yeah 26.4.1 fixes the issue
