This is an odd one......

When I first set-up Zoom I gave my profile name + a room number which then appeared on the video when I'm in a Zoom meeting. BUT. The room number is no longer valid and I want to edit and delete it. So I edited my profile and it was removed from my profile. BUT IT STILL SHOWS ON LIVE CALLS ON THE VIDEO! I can't get rid of it! Can anyone suggest a fix to remove it please?
