Is it possible for the Host to prevent just one person from sending a chat the group, i.e., Everyone, but allow others to do that? Can it be set so that only the Host can send messages to Everyone?

I've been in meetings where I don't see "Everyone" on my list of who I can send a chat to,  meanwhile I see (1) the Host sending a chat to Everyone, and (2) non-Hosts sending a msg to Everyone as well, all the while I can't. 

Zoom Version: 5.17.7 (31859) on Windows 10 Enterprise 22H2.

Zoom recently (last few weeks) started showing a notification (red disc containing white number) on the desktop app, both on the launch bar at the bottom of the screen, and in app against 'Team Chat'. 

I have checked, and there are no unread messages.  I have cleared chat histories, left chats etc, but still the notification is displayed. I have restarted the app, restarted the machine, reauthenticated and still the notification is displayed.

I am out of ideas, and while this is not my #1 work priority, it is distracting as it makes me wonder if I am missing an important notice I can't see.

I saw this was an issue for some users a few years ago, but I didn't find anything useful that was more current.  Please help.  

There is one person with whom email is correct, yet she never receives my contact requests and I never receive hers.   We don't understand why,  but I'm sure there's a legit reason.
I unblocked her but still we are not able to chat.. kindly help

We have external (to our organization) members (i.e., Consultants) that have been invited to be in a number of our Chat channels.  Once that member (consultant) is gone, is there an easy way to see all the Channels that the consultant is in, and then mass remove the Member?  Or perhaps it is not done through Chat desktop, but in the web portal?  

We used to use Pingdom with Slack and it worked great. After migrating to Zoom Team Chat, we notice there is not Pingdom integration and the Zoom web hook integration is not compatible with Pingdom either. Would be nice to see more integrations for Team Chat... But particularly it'd be nice to see Pingdom and Team Chat work together. 

We are facilitating Zoom meetings with over 100 people. We want the Chat to automatically scroll to the bottom of the Chat or to the most recent post as it has done in the past. Today, we had 190 people, so the chat was filling up quickly and we couldn't find recent chats.  Scrolling down through hundreds of posts made it absolutely impossible to see them all. How can we correct this?

I thought before in older builds of Zoom, when you were mentioned in team chat (@username) I thought there was an option to make your screen flash or there were more noticeable notifications. I have low vision and sometimes I miss notifications to the dire of my coworkers.
