This problem still occurs on the latest iOS versions (26.3 Beta 2). SharonFricker has sent apns ids, so, will you comment anything about this problem? When app is in background for some time, notifications deliver with huge delay (30-40 minutes). Is this iOS problem and will it be fixed in future releases. P.S. this problem doesn't occur on all devices, but a lot of devices have this problem. Thanks!

So, can you, please, redirect this issue to Apple Notifications Team? Cause lots of users have this problem with iOS. Here's Apple Discussions Thread: https://discussions.apple.com/thread/256138255?sortBy=newest_first&page=1

There's a list of bug reports: FB19778882 FB19813796 FB19852724 FB19767262 FB20378888 FB20379383 FB20394663 Me and many other users have issue with push notifications. To reproduce this you should do this steps: Lock iPhone and make it idle for 10+ minutes; Send any message from third-party app that uses push notifications (WhatsApp, Telegram); You can see, that it doesn't deliver. It delivers immediately when I unlock iPhone or go to the app. This bug reproduces on iOS 18.7 and 27.
