On my iPhone 6 with IOS 10.1, Safari and VoiceOver will not let me move by character in multi line edit fields like the edit field for this post. Single line fields, like sign in fields seem to be fine. This is with the rotor set to character and flicking up and down, which only results in the end of line sound. On the mobile Facebook site with Safari, the multi line edit fields allow me to only move one character, then gets stuck, reading the contents of the edit field and the cursor position in which it's stuck with up and down flicks. Also, the left right and up down keys on my Zagg bluetooth keyboard do nothing in these edit fields with quick nav off. This is all I have had the time to test, so far.
I plan on reporting this bug to Apple accessibility. It seems from other posts that not everyone has this bug. What are you all experiencing?
