Ok. After stumbling on to the NEW location of the mysterious 3 dots (you have to gently long-touch the PDF file within the note), I found the menu to select "annotate".
One major problem though, when I select ANNOTATE, the PDF is loaded and is about 2 inches wide on the screen with no visible way to zoom in. In the prior version, you could use two fingers to zoom in. If you do that now, the app starts drawing instead.
Any suggestions?
Thanks again.
