I was unable to join a meeting today despite entering the meeting ID and passcode from my own account page, getting a "Sign in to join this webinar" message every time I hit the join button.  

I have a Chromebook and use Google chrome as my browser. This is the first time I have ever encountered this issue despite using Zoom links from the same company twice a week, every week on the same device. 

I then noticed that despite having the "stay signed in" box ticked on my sign-in page, Zoom never keeps me signed in, so I was stuck in a loop of always getting the same message. The host sent me a direct link and I had the same issue:

"The host requires authentication on the commercial Zoom platform to join this meeting. Please sign in with a commercial Zoom account to join."  Previously, hitting the sign in hyperlink on this same message automatically signed me in and took me to the meetings no problem.  What's changed? Is there anything I can do in settings to stay signed in. 

I now need to use the phone app to access meetings, but this is a temporary measure not usually allowed at work.
