I was very pleased to see that Synching between Family Trees located on your computer via FTM and online in Ancestry was finally available. This was something that I had requested.

Unfortunately it doesn't appear to be working correctly. Managed to sync the very first time but any subsequent changes I make in FTM are not uploaded into the linked tree in Ancestry.com. However, if I make a change to the tree on Ancestry.com, the changes are downloaded to FTM.

Any ideas?
