Fresco increasingly glitches and crashes for me, getting frustrated

 I have attached a photo of the most recent glitch. I have had files that were completed for over 24 hours and since I was connected to WiFi, presumably uploaded to the cloud, revert back to my beginning sketch. My signature from that file suddenly showed up in a new drawing I was working on after fresco suddenly crashed. The drawing I attached below was another victim to a crash and I lost hours of work on it. Today, after reinstalling fresco and making sure my iOS was up to date, I get this weird glitch off to the side which I have circled. Is anyone else experiencing this? Until this started happening, I really loved the fresco program and this is so upsetting to me. I want to be able to trust that my artwork isn't going to be destroyed.
