I'm still attempting to get my fairly large tree synced using TreeShare, and it's a test of wills.
Often I will get the same person listed twice on the RootsMagic side. I have verified that there are not two people in RM, and when I resolve one of them and accept the changes they both go away.
Sometimes in a flurry of clicking that comes with TreeShare I'll make a wrong click and the only option is to cancel all the changes and go back and redo them. This is annoying, being able to undo the last change would be nice. Obviously not having to click so much would be better.
Also in a flurry of clicking you may miss an event or sources, and it's not always clear which you've done and which you haven't. I see that there is an attempt with the red/yellow, but for some reason with sources that doesn't always work.
