I noticed something weird yesterday in beta 6, (it could have been in earlier betas) but if you kill an app, then immediately try to open it, (sometimes it takes a few times) the app will crash. I can duplicate it on pretty much every app, including the feedback app, Chase etc. Its as if killing it doesnt fully kill it and causing sometime of network crash. I cant duplicate it in iOS14 at all so im thinking its something on how apps are "killed" (or not killed) in ios 15. I also cant get it to happen on iPadOS15 just iOS15. Weirdness.
