Thank you for your response. I am happy to hear that your problem resolved itself.
This problem has persisted since Feb 9. I had someone at Evernote help tell me that they were working on a fix for the problem and it would be resolved within 48 hours. That was on Feb 11. Yesterday this person tried to tell me that I was being blocked for security reasons and that I should use a VPN. When I responded that the Windows PC on my network had no problems he said he was going to turn the issue over to technical support. I haven't heard anything since then. Very frustrating.
