lost progress and broken signs

in my personal server i logged off and then i lost all my progress. when i type on signs it shows nothing, but when i click on it it says theres text? also mobile is broken. when i type in cmnd blocks or signs the gameplay controls are still on(w, a, s, and d make me move, i opens invite, and sometimes random buttons close it.) I have to type in a new tab and then copy+paste into there whih is really slow and tiring. also, in mobile you cant customize the controls, it only shows sensitivity and autojump. otherwise its a good game and i have fun with my friends!
