Buttons do not work conveniently.

Difficulty making any kind of selection: cannot easily switch items in inventory, cannot easily select a world or realm to join, cannot easily navigate settings menu (scrolling or selection)

Does not affect mining once in a world/realm, so this isn't exactly a lagging issue. Does not affect anything on my iPad, on happens within the Minecraft app. 

How to Reproduce

1. Try to enter world.
2. Tap once. (Highlights, but does not select.) 
3. Tap twice/thrice in quick succession. (Sometimes works.)
4. Once in a world, mine a block. (No difficulty.)
5. Now try to switching inventory items. (Difficult; not apparent in the video.)
6. Open inventory. (Selection takes two taps as well.)
7. Try to scroll. Notice that it highlights but does not select.
8. Attempt to exit game. Every one-tap highlights but does not select the option (In the video, alternating between "quit game" and "feedback" does not result in either being chosen. 

Expected Results

Making a selection with one tap. 

Observed Results

Making a selection with two or three taps. (Extremely frustrating, would make attacking mobs difficult if holding the wrong tool and result in a quick death.)
