It happened again to me today. It happens when I'm running Evernote on my iMac. Suddenly it locks up and tells me I need to upgrade or revoke. This time, however, instead of listing two iPhones, it listed one iPhone and an Android. I don't own an Android device. So, I revoked the Android, signed out of my iMac app and iphone app, created a new password and signed back in. So is Evernote staff believing this is happening from insecure accounts?
