I tried but I guess I need help. I didn’t see it under account or profile? I didn’t see it where I changed the last part either. Actually that was under account...
Click on the “profile” image on the left of your page.
Click on “edit profile” at the top left of your profile page.
You should be able to change and save new name.
I just changed my name to Lakeside Granny, imagine that?
I got on Twitter. I just opened a new account = used my same handle, JudyinCanada, but put a 1 at the end, because it said there already was a JudyinCanada. Pretty sure that’s me from last time I tried, but still couldn’t get back in.
