Invitee is Told "I'm unable to find myself."

Jim Hunt

She is on her tree and in the administrator's tree, but can't be found? It says to ask the admin for help and that it would send me a chat. I haven't seen a chat and find only messages that two folks want to join, duplicates of emails I received. I had already approved both and they are shown as members of the group.

So, how do folks use the tree once they've been approved?
