On August 8 I emailed Apple Accessibility, asking if the iPhone 15 Pro had any serious accessibility issues. This morning I received an email reply from Apple Accessibility, which stated:
"Thank you for your email. We are aware of an issue with VoiceOver where focus may occasionally shift to the top of the page. Our teams are exploring solutions for this for iOS 17, which will be releasing in the fall, and will be available for your current iPhone model.
