I imagine this could be difficult with an app that changes as often as zoom. However the mandate for a passcode to access a meeting is no longer in effect. Could you please allow Calendar to set meetings without this unnecessary restriction? [In fact, the box that appears when a "passcode" is not designated says "Meeting Passcode or Waiting Room is required." Well, I've selected the "waiting room" option, so a passcode should not be necessary...]

So far, GOOD!!!

it can not install in my computer

My first two experiences were very good. No complaints on them. The next two times I was not able to hear the zoom meeting. I could not find anywhere to turn the sound on for them. I have a PC desk top and separate speakers. The mic in the lower left corner was not on the 3rd & 4th meetings. Only a headset, which I don't have. How can this be corrected so I can enjoy the zoom meetings?

It works and is easy.
