Disappearing Markups on PDFs
As i edit PDF documents on my iPad Pro using the Markup function, i find that the markups disappear when I reopen the document to add more markups or it randomly saves some markups but not others. It's frustrating as I invest 10-15 minutes filling out a pdf form and the entire document is blank when i send it or reopen it. I tried periodically closing it and reopening, hoping it would save all work at that point, but it's random as to whether it saves the work. It would be a great feature if it worked reliably. any suggestions ?
