I have the same issue as above. I was asked to "unsync device" for the extra devices not covered under the Evernote Basic. I only have two. This happened twice this month. When I checked the access list in settings, it included an iPhone from Japan. I don't have an iPhone nor am based in Japan (01/24/2019 188.8.131.52 (Osaka, Japan)). Just a few hours ago, I had a Samsung listed in my device! I am not using a Samsung...I have seriously considered subscribing to the Premium package, but I am having second thoughts now since there is a huge issue on security.
