Hey @webdev, @flippyhead, @vtorralbes, @erichhansen, @spsantos, @nitin1, @classrooms, @stw, @dev-smabc, @khizar.zech, @developer-whova, @icordova,
We have implemented a fix. Please let us know if it is working for you now.

Hi, I did a test, it’s working.
It’s working now. thx
It’s working now, butit was reported broken very early today, and it took hours to even show up on status as a problem. Why so long for the ack?
Happy to hear it is working for you @spsantos, @webdev!
Apologies for the late update to status.zoom.us, we will be faster next time.
Thanks,
Tommy
