I upload my RootsMagic tree to a new Ancestry.com tree. TreeShare seems to work beautifully.
EXCEPT on the third day, the RootsMagic tree and the Ancestry tree UNLINK!
NO, I did not intentionally or inadvertently do this. They just unlinked spontaneously. As I recall, it occurred after I selected the <TreeShare for Ancestry> button that was placed on the tool bar then selected <login>. I had done this many times over the last two days with no problem.
