It's 8/24/17 and I just installed the latest version, logged in (no trouble even with 2fa), tagged and clipped. The notes synced over to my desktop app right away. I'm not sure what the trouble has been with prior reviews. Someone mentioned that you need to be logged into Firefox first before you can log into Evernote. While I can't confirm, I will specify that I *am* logged into this addons page, but I am *not* signed in to sync when I check the upper right menu icon. Hope this helps.
