All notes adding using "Add Note" have disappeared!

[cohenville]

I am using Nitro Pro 10.5.9.9.  I spent hours marking up a document using "Add Note" the other day.  I saved the document numerous times during this process, and again upon exit.  When I went in today to continue where I left off, I found that all of the notes I had added were gone.

Any suggestions on where they might have gone to; how to retrieve them; or how to avoid this situation next time?

Thank you!

If you're on Windows 10, does Edge see the notes in the PDF?

In Nitro, normally, you'd see the notes in the document, and the way to see all of them is to click on the yellow sticky note on the bottom left hand corner.
