That wasn't the problem. I was properly logged in. But I resolved it by deleting Evernote completely, including all linked files such as the preferences and other files in the Library, and re-installing. Worked fine after that.

I just upgraded to a new Mac Studio. Installed Evernote and even though I'm logged into my account it shows 0 notes and 0 notebooks. But I have 17 notebooks and thousands of notes. The web version shows all the notes, as do my iOS devices, but even after a few hours nothing is showing on the desktop and it isn't showing up as a device.
