I went back to the email I received - and was able to click on the email and bring it up. It contained a symbol in the lower left hand corner - and I wanted to change the
date, but nothing happened when I clicked on the symbol. I then went back to my individual evernote account (not on the Web version) and was able to find the note and
change the due date. So - no harm - but perhaps the Web version does not have that feature yet?
