Restore a previous file version from the document cloud?

Thank you kindly for your reply, Meenakshi. I was using the Adobe Acrobat application on my iPad Air. I was working with a PDF file for three days. I think that the file probably synced to the cloud a couple of times during that period. After three days, when I was back home from the conference, I connected to Wi-Fi and saw that the application was “syncing”. However, it appeared to get hung up in that process. I restarted the application after a while and then the file in Document Cloud could no longer be opened on my iPad or my computer.

I checked out the link below. Although I see a couple versions of the file, none are from any time prior to the corruption. It would have to be dated between June 17 and June 19. Perhaps there is a copy somewhere?

I appreciate your help. If possible, it would be great to recover the notes that I took during the 3-day seminar.

Thanks kindly.
