I notified tech support about constant duplicate notes being created and their response was disturbing. I am curious if other users deem this to be as problematic and cumbersome as I do, especially since I don't recall this happening in older versions, and certainly shouldn't be happening in an application wherein syncing is a key feature:
Here is their response:
Regarding the duplicate note warnings, at the moment, Evernote does not support real-time editing. When a note is edited in two different devices before a sync has taken place, two copies of this same note might be in conflict. When this happens, the note duplicates. You can then view both versions of the note and the conflicting version from the server, then manually apply any changes that couldn't be merged automatically. Once you're satisfied that the original version has all of the changes, delete the duplicated version. Moving forward, to help us to isolate this issue, when editing a note, make sure you are online, the note is not open in any other device. This way, if your account is syncing properly, you should have its latest versions. Also, when you're done editing the note, sync and then close the note so it's ready to be synced to all your devices.
