Thanks for the update. Is there any workaround at this moment?

Ah sorry I forgot to mention the FB number. It's FB20214148 Edit: in my app while device using dark mode, the tabbar floats on top of the WKWebView and when the issue happened, the tabbar's background color changes from black/dark to white/light.

Im also facing this issue, happens when I open a .mp4 video file. The view reposition itself after switch tab (I dont remember/not sure) or switching between apps

I still see this issue, Im using Xcode beta 4, running test on iPad with iPadOS Developer Beta. I tried [self.tabBarController setTabBarHidden:true]; in viewWillAppear [self.tabBarController.tabBar setHidden:true]; in viewWillAppear [self.tabBarController setHidesBottomBarWhenPushed:true]; in parent view controller

Today when I try to resize the window, I find out that it can't be resized freely like other apps (reduce width, height) and I can only make it smaller but with the same ratio. Turn out it is the UIRequiresFullScreen key (second one from my Info.plist) that keeps the window to be fully displayed or at least kept the default ratio. Removing or changing it to NO/false solves the issue.
