I opened my vdoopad doc today and found that several links and pages are gone. It's very strange, but I would never delete those pages because they're very important. Not only are the links gone, the pages themselves are gone (I did a search).
I'm not sure when this happened but likely over the past week. The vdpad file is stored on my google drive and I can see the activity/edits that have been done to it, but I don't see anywhere that those pages have been deleted.

In any case, I would like to see if I can restore an older version of the document from maybe last month. Do you know how I can do that? I've tried using google drive restore but the vdpad file does not have the time icon next to it, so I can't see older versions, even though I can see the timed edits to the file.

If someone knows what likely happened, please also let me know.

Please help!
