Sync problems

What issue do you have?

I recently migrated about 4500 notes from Evernote, with about 7GB attachments. I am syncing to OneDrive. I have this setup on my desktop, iPhone and iPad, all good (eventually). Now, I want to add to my laptop. It works for a while and then says "An error occurred in the data store." It doesn't seem to do a partial sync, so I start from scratch each time. Virtually no notes have appeared on the laptop so far.

Any advice?

(Could I just copy the profile directory over? Or does that mess up because of some instance number? Seems sketchy...)

Thanks!
