I vote strongly for returning this ability to sync as well. I am getting far more duplicated notes now with conflicts. (a better conflict resolver would be nice too).
This is esp. true if you use the Windows app and the IOS app a lot. The Windows app might sync better (although certainly not perfect between two Windows devices), but the IOS app does not seem to sync the same way.
I like almost all the changes in the recent release. This change (removing manual sync) I do not. I spend more time cleaning up conflicted notes and reduces my efficiency. The opposite of what you want with EN.
