Every so often I get an email with the subject "We were unable to add your device", saying "You are able to sync your notes to a maximum of 2 devices using Evernote Basic". Problem is, I'm only using two devices (Android phone and Windows PC). When I go to revoke a device it keeps saying there's an iPhone accessing my notes... and I don't own one. So is my account getting repeatedly hacked or is this a bug? Anyone else getting this issue?
