Mac SSO in newest build FAILs

I have an enterprise account and my employer. I'm on a Mac but the newest build of Zoom refuses to take me thru the SSO process to login. 

Previously at login, I clicked on the SSO button and it took me to the employers portal I signed in, and then the Outlook widget set Zoom mtgs on my calendar.

As of last week, the SSO button does nothing but login me in under my corporate email to a FREE ACCOUNT, with 40 min limit. This is a ZOOM BUG, please fix!
