I had other sync issues and ended up unlinking my tree (major pain since it was shared with a number of family members) and uploading a new tree. Had no problem with sync for a few days.
Now each time I've sync'd I'm getting the error shortly after the sync starts that says "The last sync failed. An error occurred while "Analyzing online changes". Please try again later.
I've compacted the file and rebooted my computer (which fixed the last sync error).
Any thoughts on what this means or solution for it?
