Great app, but buggy.

Ive been using this app for so many years, I cant count them. Its always been such a great tool to use, and I love it so much. I would give it 5 stars, but unfortunately its been quite buggy lately. Often, even after saving my canvas, it will destroy it and not let me undo it. Like, Ill open a different app for a moment, and when I go back to this app, the entire thing is basically murdered. It is extremely distorted, basically appearing as a bunch of straight lines dripping down the canvas in the colours I was using. I cant hit undo, when I try to reload the project its still the same, and theres nothing I can do to return to my actual drawing. This has happened multiple times over the past 2 years, and its quite frustrating considering the amount of effort I put into my art. I simply do not have the time to put up with this. I cant afford to spent hours on a portrait, only for all my work to be literally wiped down the screen. The app is absolutely wonderful, but this bug has made insanely furious.
