Misleading message on Meetings registration confirmation page

[Mags19]

A user registered for a meeting 20 minutes before the start time. She got to the "registration confirmation page" that had the message, "You will be automatically redirected to the live session when it starts. Please do not close this browser." The blue "Join" button was also displayed. She sat on this page and was never redirected to the meeting. Is there some bug in the system at the moment?

I was able to replicate the problem myself today. Once I clicked on the "Join" button, I was admitted. But that was ignoring the message telling me I'd be redirected automatically. What's going on? How can we ensure all our registrants get into our meetings?
