Yes I know that a manual sync option is still possible.
However, tapping through multiple options menus is frankly a pain in the...insert your favourite anatomical feature.
The inability to quickly and easily sync frequently results in conflicting notes for users that switch between desktop and mobile versions. By placing a sync now button on the home screen of the mobile app, these annoyances will likely be reduced significantly. At least that's what my experience was when there was a quick sync button.
So please, bring it back home!
