Why does the app glitch and remove everything in the frame

The app glitches sometimes and kicks me out and removes everything in that frame. I was working on something huge with 22 different franchises it took me more than 3 just to finish the outlines and then today I started to coloring the thing to finish it but then the glitch happened and everything I worked on (all of my extremely hard work) was removed gone, reduced to atoms. It didn’t remove most of it it removed ALL of my hard work. I want this glitch removed if you can. I don’t want this glitch to happen again
