Does yours sync every change? I just made a test change to an event description of a single individual and synced. It didn't change in the online tree. I noticed when I synced that I received the message attached, and remembered that I received the same message after the place name resolution and spell check.
Changes I make to my online tree sync into FTM, but I am realizing now that any changes I make to FTM do not sync into my online tree.
