logged in under a colleague's account

[jsnyder42]

I had to log in under a colleague's name several days ago (Carl Richardson) -- I'm trying to get into a separate meeting now but it's not letting me in as it thinks I'm my colleague!  (I have been able to join under other meetings ...)

How can I ensure that I'm able to enter all ZOOM meetings under my own name (Joel Snyder).  Please help!
