Switching Accounts no longer works

I have two Zoom accounts I log into and switch between.  One is work, the other is personal - they have different avatar images so I can tell them apart.  If someone from my company and I are logging into the same meeting that someone ELSE sent the link for, I have to log in through my personal account so that my colleague and I are using different accounts to enter the meeting to avoid connectivity issues.  I used to be able to simply "switch accounts" to the one I needed to use without needing to fully log out and then back in.  Now, regardless of which account I appear to have switched to via the computer app, when I initiate the Zoom, I enter the meeting under my work account.  Interestingly, if I'm in the waiting room, my avatar shows me as entering via my personal account, but once I'm actually IN the meeting, I'm in as my work account.  All other functions switch appropriately when I switch accounts without actually logging out.  It's just when I try to enter a meeting.  This only began about 2 weeks ago.  It was working find before that.  This issue seems to have started at about the same time that the ability to message someone directly - regardless of the settings - stopped working as well.
