"The last sync failed. An error occurred while "Analyzing changes from Family Tree Maker". You may want to restart FTM and try again later."
I've been getting this message for months. I have a 120,000+ person file and try to sync daily. In the past several months all syncs from FTM to Ancestry have failed. I never sync from Ancestry to FTM. Compacting and or restarting FTM over and over and over does not help.
