Meeting links never work, participants are asked for passcode

I have zoom integrated with Google Calendar, and I always add a zoom meeting when I send out an invite. I integrated zoom with my own calendar originally, and then my workspace admin integrated it with everything.

9 times out of 10, possibly 10 out of 10, my invitees can't join the meeting. Zoom will ask them for a password (which should be baked into a link), and the password in the calendar invite doesn't work. I'll inevitably slack them a zoom link using "/zoom," and it will actually open up the zoom I'm already in and work just fine.

It's gotten to the point where my admin turning on zoom for our space is destroying my ability to talk to colleagues and customers, and I can't seem to fix it. Does anyone know of a solution?

I don't think this happens for my colleagues, but I've started setting up hangouts with them whenever I own the meeting. It doesn't happen for all of my meetings, but I can't tell if that's just because some of them are older meetings. Almost anything new that I schedule is totally broken.
