Did you have all of your history before changing your name? Or did you change and then have your history migrated over somehow? I'm trying to be patient but also curious how this is going. I can find my old account but I can't login to it. I don't want to foul things up anymore than I potentially have at this point.Go to the 3 lines in top left. Click on your pic. Scroll down thru the adds and go to profile. I was able to change my username there. I’m currently on my phone. I can only access On3 via my phone. I’m unable to on my laptop. I know things are frustrating. I share that. I detest change. But I’m trying to be patient.
