I also hate this new upgrade, not fond of it at all, it's totally screwed up my user experience.
So now, i'm still working on the older version, which was a lot more user friendly & personally my preference.
Also a premium customer, but won't renew my subscription, as I can pretty much get the same from many other apps such as Todoist etc.
This is why I got evernote in the first place.
Put back the damn sync button !!!!!!
