I cannot sync my Mac app. Everytime I try the wheel spins and I get a red cross after a few minutes. When I look on the web app or iPad about 90% of the data is present but 10% is missing.

I am on version 10.0.54

If I try later versions of the Mac app the data is then missing on the same Mac - which is very strange.

I do not want to use 'Clean Sync Data' as this warns me it is going to delete my local data base on my Mac which is the only place where the data is correct.

Even with the 'good' 10.0.54 version there are now so "A version is being uploaded on another device" errors on one or two of the notes.
