I just lost two weeks of work. I'm devastated. This isn't the first time the app has crashed and suddenly deleted my layers only for it to restore them two hours later. This time my line art that I've been working on for the past two weeks hasn't returned. I've tried everything to work around the crashes by making frequent back ups but this time the app crashed while I was making a back up. I'm so upset. Please don't download if you want to make a lot of projects. Find a better app.
