When I open Evernote 6.9.1 on OS X El Capitan, I see a banner across the top reading "Critical update available" and an "Update now" button. When I click the button it takes me to the App Store, which lists the current version as 6.9.2, but there is no option to update Evernote -- the only option is "Open." If I click that, it takes me back to Evernote. There is no "Check for updates" menu option in Evernote's help menu. I suppose I'll have to download 6.9.2 from the Evernote site, but something isn't working in your App Store release.
psfblair replied to keenerguy's question in Evernote for Mac Requests (Versions 7.14 and under)I've added my vote. It's incredible how many features I don't care about have been added to this product where something as basic as this hasn't been added.
