Same thing happens in our app, but not in all the pushed view controller. Have you tried open Settings General About? It's much more weird. It reads the first row then go back to focus on General button.

Seems although VoiceOver recognition doesn't exist Settings Accessibility Voice Over in iPhone 7/8, the iOS 14 new features especially text recognition exist which is not stable and inconsistent with the behaviour on iPhone X/11/12, and we do not have a way to turn it off on iPhone 7/8....

Same issue with Settings General or Settings Wifi, voiceover now picks a first element below instead. Although there is workaround to force to focus on the nav title or back button, just wondering is there any docs explaining why the default behaviour changes? A workaround: UIAccessibility.post(notification: UIAccessibility.Notification.screenChanged, argument: yourElement)
