With the new tricky trials update, the hot-bar (item bar or whatever) is nearly impossible to hit if finger is even slightly touching the non-hot-bar section of the screen. This was NOT so after switching to the Classic UI profile but remains with the Pocket UI profile. Whenever not only touching the hot bar, the system assumes the player is trying to interact with the world (placing or hitting). I would prefer, on iPhone, the Pocket UI profile, and see the Classic profile as more difficult to use. This was on an IPhone 12.
