I loved it till.... – Color By Number! Pixel Art Review

I loved this app and got on it everyday until I got on the app and colored a stamp. I got back on the app later that day and all my progress was gone. Now every time I get on the app a little bit of my progress is gone from the last time I was on it. Also EVERYTHING i have progress on is all erased so now I have to go back and fix it just for it to be erased again! PLEASE FIX THIS PROBLEM!
