I don't frequently use VoiceOver text editing, but I was using it today in order to write some training notes. I was working on an iPad Air with iOS 9.0.1. Basically, I can't get editing to work reliably; I've tried a soft reset, which had no effect. I'm using the body text of an email as my example. I turn the rotor to words and swipe down until I reach the word I want to remove. Next, I turn the rotor to Edit and swipe down to arrive at "select". I double tap, and the word is selected. The usual black row of options appears on screen and VoiceOver speaks "[selected word], show more items, menu item". If I swipe up at this point, the black menu disappears and VoiceOver speaks "unselected, [selected word]". The same happens if I swipe down.
I can get to cut by tapping on the black bar and swiping left or right to "cut" but this isn't any use for someone with no sight. Since the VO focus appeared to be on the item to the right of the black bar (but didn't show) I tried a left swipe. This took me to the email Subject field. A right swipe took me to "minimize draft". Oddly, after I've done all of that while writing this email. A second attempt at swiping up after selected has worked correctly and I can swipe up to cut.
And now it's working every time.
I then dismissed the mail app and restarted it. This time, if I swipe up after selecting, I hear "unselected, [word] The issue has returned!
I've not reported to Apple yet, suspecting I might be doing something silly. Any advice, please?
