My ipad deleted what I edited on a photo with markup
So I took a picture and edited (on my iPad Air 4th generation, latest software 16.3.1 ) with markup, doing some important notes on them. A few days later, today, I wanted to take a look at them and I could not believe my eyes. The markups have disappeared, leaving me with the original photos with no notes on them. I can't imagine how something like this happened... Any way I can get my markups back? I took some important notes and I need them.
