Uploading commented pdf files to Google drive

I open the file from Google drive and ask it to save (or open in Acrobat Reader).

Then I work on it .. annotate, comment, draw etc on the file using Acrobat reader.

After that I say “share file”... there are multiple options including “save to google drive”, “gmail” etc.

Earlier when I chose these options .. it would ask me whether I want to save original file (where comments can be edited) or flattened file (where comments cannot be edited). I used to choose “flattened file”, and then when I gave someone my google drive file link, or emailed to someone, or put it in a shared folder ... they could see my comments, annotations and drawings.

Now when I save to Google drive or even try sharing by email through gmail ... It does not give me an option to share ”original” or “flattened” file. Further, when I save / send ... none of the comments are visible any more, although they exist in my adobe acrobat reader version of the file.
