Hi, After resetting all my iPhone's default settings, I've finally discovered how to stop VoiceOver from jumping around whilst in share-sheets and certain apps, i.e. the App Store, Mail, Facebook, etc. If this bug is driving you as balmy as it has driven me, try out the following, I'll be interested to see if you have success, as I have. Go to:
Then under the first heading which is:
Hardware Keyboards, turn off full keyboard access. I am not sure why enabling this feature invokes this bug, I intend to report this to Apple at a civilized hour later today, NZ time. Since turning off full keyboard access, I have still been able to do basic commands on my bluetooth keyboard. Having said that, I'm not very familiar with all the keyboard shortcuts, so I'm not sure what will happen as a result of turning off full keyboard access. I hope this is helpful in some way for anyone who has experienced the tyrany of this tiresome bug.
