I noticed the same for my app. iOS 13 and XCode 11, the form was extended to the edges. Then I switched to iOS 14 and XCode 12 with no code changes and then the form all of a sudden has a different style. I had the same issue with list. Before extending to the edges and then not. I solved that by adding a .listStyle(PlainListStyle()) to the list. I guess it's something similar for forms but I can't figure out what.

Version 14.2 Beta works for me too!

Thanks for sharing the response from Apple. In my case my app is running in the foreground when I receive these background notifications but still only 2 or 3 arrives then it is blocked for a while. I knew that they weren't guaranteed to arrive in earlier versions of iOS as well but I though that at least if the app is running in the foreground then they should arrive. And they did, all the time in iOS 13. It doesn't save much battery to block a notification for an app that is already running in the foreground.

Same issue here. After updating from iOS 13 to 14 I have issues with lost push notifications. I was hoping it was a beta issue but I have the same issues after updating to release version of iOS 14.
