Evernote syncing has been having issues for the past couple of months (ever since the big user-noticeable changes were launched.) I typically update the same note on my Mac and on my iPhone. I have been doing this for years (evernote premium since 2011) and never ever had an issue.
Then in the past couple of months, I kept getting 2 versions of the same note. When I dug deeper, I saw what was happening. I update the note on my iPhone. Then I move on to doing something else. The evernote app on the phone does not sync immediately (this was never the case before). Even hours later, when I go to my Mac and update the same note, the version on the phone did not sync, therefore now I have 2 versions of the same note.
This is VERY frustrating. What used to be a very simple and reliable user experience turned into a nightmare! I can't rely on my notes anymore. Please fix this issue! I don't care if you take back all the bells & whistles you've implemented recently. Really! If the basic syncing is not reliable, the app is not useable. Give me the old evernote back!
