I use Android on mobile and Mac App on Macbook. The other quirk on Android is duplicate notes.
If anything disturbs the save - unresponsive green arrow or simply it goes poof in the middle of an edit - a duplicate will be generated with a time of "Just Now".
If I edit a note on the mac and later (minutes or hours later) try to edit that note on Android I discover that I am editing the older version and a duplicate will be created when I exit the note. "Server sync" has become very unreliable in the last few months. It's gotten to the point that I try to only edit on Mac and read on Android.
