Microsoft Print to PDF no longer flattening files

Hello,
Using W10x64 Pro Verison 1909 Build 18363.778 with the APR 2020 update.

I don't know when this started (perhaps with the newest update??) but if I want to make changes to a pdf I make changes with Adobe READER using comments then I print using the Microsoft Print to PDF it goes through this flattening notice and the comments are no longer there but the text within is stamped onto the page.

I have been doing this for YEARS.

Today it did not work! I add the comment, I print using MS Print to PDF and when I open the file, the comment is completely gone including the text I put on it.

Fortunately, I have a different way of accomplishing this but it may go away in the future as it is evaluation software.

Suggestions? Is there a now a registry hack?

Thanks!

It seems to work using PDF-XChange Editor (free), which is the PDF reader I use (and have used for years). But you can also save the modified PDF directly, no need to use Microsoft Print to PDF (al least for some editions, there may be restrictions in the free version).

What seems to work? Using Microsoft Print to PDF to flatten the PDF? The print function does not have anything to do with the program calling that function.

Also, simply saving the PDF with PDF-XChange does not work.
