Have been syncing OF right along using the OmniSync server until today. Out of the blue on my iPad, it says "Replace your database and start syncing?" and that the database is incompatible. The choices are "Keep Device Database" or "Keep Sync Database". I assume the former means "don't sync" and the later means scrap the recent changes I've made on the iPad and use what's on the server. I assume my only long term answer is to "Keep sync database", but just verifying here. Also, anything I could have done to prevent this?
