I’m so angry right now. I spent hours upon hours working on something on flipaclip, my phone restarted two times while using it, they were a couple hours apart. The second time it happened Flipaclip decided to delete from EVERYTHING I WAS WORKING ON except the two things I had already previously downloaded. If this doesnt get resolved im gonna for real leave a one star on the App Store.

I forgot to add I can’t make anything else on the app because it says e-215. I tried to look up e-215 but I got no answers 

nah sis I left a one star anyways. Can anyone recommend better apps?
