Hello,
I'm writing to this forum because we are facing a bug with silent notifications with iOS 11.
These types of notifications are not delivered, even if our app is in foreground and connected to power. But silent notifications are important for our app. Actually we have seen some threads which talk about this issue (https://forums.developer.apple.com/message/235673#235673 or https://stackoverflow.com/questions/44796613/silent-pushes-not-delivered-to-the-app-on-ios-11).
In these threads, we noticed that there are some changes and some fixes with iOS 11.1 beta.
So do you know when Apple will push this fix to the released iOS ? Maybe an Apple engineer could see this thread and answer this question.
Regards
