There is no option to do anything when clicking on the icon in the Safari toolbar, so there is no way to access Activity Logs. On clicking the toolbar button Safari attempts to connect to evernote.com, but all that appears is the message, "You must sign in using the Clip To Evernote toolbar button ..." This is Safari 10.0.3 using Sierra 10.12.2. I've tried all the standard stuff (uninstall, reinstall, restart, reset, etc.); nothing works. It hasn't been working now for a considerable time.
