Hi. What does "not working" mean. Not loading, not syncing, throwing an error, crashing? And is this Mac / Windows / Desktop / Tablet / Web etc?
www.evernote.com's DNS is not have AAAA record.
therefore cannot access via IPv6.
should add IPv6 address to server.
So when will ipv6 work? So many years you can not turn on ipv6? And yes, I also have the same problems and have been looking at this topic for a long time!
