When I'm using Safari, and try to read the page with VoiceOver, the browser completely hangs. Even when I turn off VoiceOver, Safari still doesn't respond to any taps or swipes. The only thing that helps then, is to completely shut down Safari (removing it from the app switcher). When I then restart Safari, the app crashes and restarts. After the restart, the app works as expected, until I turn on Safari.
I started having this problem after updating to IOS 11. The 11.0.2 update seemed to make it happen less frequently, but after updating to 11.0.3, it happens every time when I open Safari.
I'll file a bug with Apple, in the hope that they fix this ASAP, but is anyone here having the same problem, and did you find a way around this?
I didn't see this in the list of IOS 11 bugs.
