I have been disgusted with the accessibility of apple tv since tv os11. I'm currently running tv os 13.4.6. My apple tv is very sluggish, vo doesn't respond well. It's acting like an old iPhone does when it's old and out of date. I have the fourth gen. When I call apple accessibility the reps say they don't know much about the apple tv and it seems like apple does not say much about accessibility on the apple tv. Makes me wonder if the apple tv will soon become obsolete.
