Mobile bugs/problems (new update

now the update (recently) have been prettu good for me expect 2 things. Simple one, i cant see where my friends are when there online, i know if you click on their profile it will show join them but in my opinion i liked the old version of the friends list more, but that wasn't really my main problem. The msin one is on mobile for some reason i cant click buttons or flick levers and its annoying me, especially since i enjoy building here and that threw me off. This wasn't a problem for me yesterday though… any ways to fix any of this? Also noticed pvp with fists is off, i can still shoot a bow easily but pvp is weird, ill explain more if needed.
