Hi. I have just taken delivery of my new braille display from humanware. The first thing I always do when configuring my display is to reverse the thumb keys on the front of the display. This has worked well, except for as soon as I connect to my iPad or iPhone. The keys reset them sells to how they originally were, or at least that is how it seems. I have looked through all the Braille options I can think of, both under voice-over and under the display itself, but no luck. Can someone help? Thank you.
