I have been experiencing an issue with my team for screensharing and audio with Zoom. 

Basically, screen sharing option is missing for participants. The only options they see are Participants, Raise hand, Meeting info and More.
They are also unable to join with an audio in a Zoom meeting. The issue doesn't seem to happen for a host of a meeting. 

I first noticed this on MacOS devices but soon realized this issue is coming up in all browsers (Chrome, Edge and Safari) and Windows as well. Using the latest version of Zoom on macOS and windows devices.

I have already checked and made sure Zoom has access to all settings in this article: Enabling screen sharing for participants in Zoom meetings

I have also made sure the global settings in Zoom admin is not restricting screen sharing. This is happening to all users in my team for any internal or external meeting where they are the participants. 

Any ideas?

I am relatively green with this technology and I would appreciate your help so I can avoid any issues the day of!  Thank you for your help in advance!  FYI, I am a pro member. 

I will be holding multiple interviews throughout the day with 3 interviewers, each joining separately.  Each of the interviewees will also join separately for their one 1 hour slot.

To make it easier, can I create one meeting link and share it with everyone including the interviewees?

And if we take a 1 hour lunch break in the middle of the day, will the meeting automatically stop, requiring us to log into the meeting again?  Should we have one link for before lunch and one for after lunch?

I am not able to launch Zoom automatically from my iPhone when someone sends me the link thru Facebook Messenger.  A window pops up saying that I have to copy the link and paste to a browser.  Is there an easier way to launch Zoom by just clicking on the Zoom link provided?  I have the Zoom app loaded on my iPhone.  I don't want to copy-and-paste to a browser...

I've had an on-going problem with classes I take via Zoom.  As the class progresses, the audio degrades.  It usually begins as light pops or crackle when the instructors and guests are speaking, and ends with so much static and distortion that no one is comprehensible.  If I leave the class and rejoin, everything is crystal clear again . . . for a while.  It seems to only affect me, none of the other people on the call.  And to clarify, the static and distortion are only there while other's are speaking, and does not continue through silence. 

We've changed our internet service, upgraded to fiber, but the issue remains.  What else can I explore?

If I were only observing/listening, leaving and coming back wouldn't be such an issue; but in some cases my role is participatory, and if I cannot understand what the others are saying, then my being there is useless.  I've had no issues with multi-hour Google or Facebook calls on the same desktop with the same peripherals, if that helps narrow the field of where to look next.

Thanks, all!
