I was playing a realm a month ago and everything was fine. However I have this issue now that seems to happen a lot. I wanted to play today, but every time I enter, controls, mobs, players and their gamertags, food bar, hotbar, my doll, my inventory, scoreboard, and even the pause and chat button disappear. I tried reinstalling Minecraft and restarting my device and nothing happened. However, I can still move and choose things in my hot bar but I don't see them.
