My Zoom app opens but I cannot launch or join meetings.

Hi, I have the same problem on 2 of my laptops since a couple of days. I can open as a host on my mobile, but nothing happens on my laptop...

Same problem here. 

Same problem here, over more than 10 minutes under all methods of starting a zoom meeting from my MacBook Air.... been doing these group meeting calls for over 3 years now and never had this problem before.  I cannot find a way to get ZOOM people them to respond.  The 'robot' response has no way of responding either
