I did an upgrade recently to 18.104.22.16834 and used the recommended default settings for most stuff. However, I have what seems to be a different pattern of performance. When I'm in Tree View and looking at some people and notice the SmartMatch indicator.
My problem is that when I click on it, the match is often to my own online tree. I don't think it showed up that way before, even though I had a lot of SmartMatches to other web trees before. It's frustrating to see a match and hope someone has listed a family member that links to me, only to click it and find its only my own tree.
I fixed this for you, you should not be receiving these Matches again.
The problem was that you had a duplicate account in our site, which contained your tree. Your main account was matched with this duplicate account. This account was created for you as you are a GenCircles user, and this is a company that we merged with a few years ago. As this was a duplicate account, I have now removed it for you.
