Thanks for the response, just making sure we're covered and avoid a rejection.

Thanks for your reply. We only see the issue when Full Keyboard Access is turned on. Otherwise, the app works as expected with left/right up/down paginating as we've coded. I've watched that video before but will watch again. This is how I got the idea to try to use wantsPriorityOverSystemBehavior mentioned around 18:48 in video.
