I have been using the markup tool in the Files app to take notes and do calculations. Today I was using it, and while I was in the middle of writing, the app froze for 1 second and restored my work to an earlier version from many hours ago. Unfortunately I lost 4-5 hours worth of hand-written work. How can I get my work back? This glitch has occurred twice today.
iPad Pro, iPadOS 15
