I use my laptop to open Zoom meetings for my clients. I do this several times a day several days a week. 
Occasionally Zoom asks me to sign in to my account from the Zoom.us page. Today I was taken to that page and told that I was trying to get on from an unfamiliar location. THIS WAS NOT TRUE. To open my account they said I should go to my email and retrieve a CODE and fill it in. THERE WAS NO EMAIL FROM ZOOM AND NO CODE. It's been hours and I've requested the code multiple times and still no code. 

I tried to phone Support, gave the the automated system my account number and then was asked for my Host Key. But I cannot locate my Host Key since I cannot get into my account to find it. 

I tried to get on a phone call to speak to a human about purchasing or billing - I figured I'd get a human that way. But it's been a long wait and the music they play is disturbing, threatening, anxiety-producing. That is so unusual and not normal. What is going on? 

Is there any way to CONTACT A LIVE HUMAN AT ZOOM? I depend on Zoom for my livelihood! 
Any advice or suggestions would be much appreciated. 

Desde que comecei a usar o Zoom, conseguia facilmente transmitir músicas, seja pelo celular, ou com uma caixinha de som.  Há algum tempo não consigo mais. Ou não transmite som algum, só minha voz, ou a voz do cantor sem os instrumentos, Alguém tem a solução para isso?

Since I subscribed to Zoom Pro my meetings freeze after about 90 minutes.
First my video freezes but I can hear the meeting and the other participants can hear me but I cannot access chat or raise my hand or do anything except listen and talk. After a few minutes I cannot be heard by the other participants and I have to restart my computer and re-enter the meeting.
I have removed the zoom program and re-installed but it has made no difference.

I am having an issue with the 2-meeting limit per user rule. I am the owner/admin for my company's zoom account (business licensed) and I have 5 other employees/users on my account.

I use an online scheduler (Acuity) to book meetings with clients via Zoom, but Acuity only allows one zoom account to be integrated so all meetings are assigned to my zoom account. 

I've currently assigned all my employees to have 'Scheduling Privileges' of my Zoom account so they all can see my meetings and take the ones that I assign to them. This is working well except when we schedule more than three or more concurrent Zoom meetings

Since all meetings are assigned to "me", it seems we can only have two concurrent meetings even if my employees run them without me logged in and/or present at the meeting(s).  

Is the way around this to designate an 'alternative host' for each meeting so now the user that I assign as an alternative host can run the meeting and it won't count against 'my" 2-meeting limit?

On iPad Pro Zoom I am trying to screen share videos whether from my own file or streaming, in control centre screen sharing is on, in zoom app the original sound is enabled, microphone is on and “share device audio” is on. But participants cannot hear any sound. And for me the volume remains barely discernible and the volume level does not change with the volume buttons.

I'm sending this more of as a bug report. At this time we've rolled our Remote Desktop session hosts running Zoom back to 5.16.2.22807. 

Unfortunately I don't have much more to add than my post but I'll give whatever detail I can as to what we were seeing. 

When launching Zoom, the zoom.exe process in Task Manager would show, and then disappear after a few seconds. 

No logs found in the log location. 

No Windows Event viewer events found. 

Turned off our A/V (Sophos) to verify that was not interfering.
