This has been an off and on problem for me since iOS 17 and I'm wondering if anyone else deals with it and if there's a solution.
Periodically and seemingly at random, when viewing a webpage with Voiceover, paragraphs will repeat themselves. The only solution when this starts happening is to close and restart Safari. Except on search results from DuckDuckGo, those will always repeat. It makes reading a whole page with the swipe down gesture impossible.
There's also been an issue where anything I type to search in the address bar will repeat every word and then the whole phrase while I am typing. It's very distracting and has nothing to do with my keyboard or typing settings (which are set to not repeat any words). It's just a Safari thing that came in after iOS 17.
I have wondered if some of this isn't to do with experimental features in feature flags but since I can't find any clear answers on what most of those do I haven't messed much with them (except to disable "scroll to text" and enable all the audio description settings).
