Just started using Filr, only have 8 users so far. 3 of our users have received the message "Inconsistent Synchronization Metadata" and have had to press the 'reset' button and re-sync all their data. I would like to understand more about this issue before we roll this out to a much larger group. I've searched the knowledge base and forums and can't seem to find much info on this error. Does anyone know more about what causes this? Maybe we're doing something wrong?
