Disappearing Submit/Cancel move on Daily games

I use an android phone running Chrome to play chess. When I make a move, the submit /Cancel button disappears to the bottom of the phone and I have to scroll down to make my move.

I know I can easily scroll down, but having several daily games it can be annoying - make a move scroll down confirm move, scroll back up, make another move in the next game, scroll back down etc.

This never used to happen, hopefully it gets back to normal soon. 

yo no puedo mandar mis movimiento 

I have a similar problem: I try out a move, but if  want to change it doesn't let me. .. the only option is 'send'.  The only way I can get back to the same game, is by clicking on the 'next game', and then open the game in question again.
