I have been experiencing difficulty when using a host provided link to join a meeting.  This is a new weekly group  meeting and it seems that my camera is not being activated.  And more recently,  the video continued to switch on and off without being prompted by me.  Is this a Zoom issue or my device?

Hello.

I am a paid subscriber. I hosted a meeting yesterday where 90 people were registered but only a fraction e.g. 30 people attended. I would like to know which attendees actually attended. Where do I find that ? I know in the past this was definitely something I could track. 

Has Zoom taken away that functionality? Please help

The names for my participants in the chat have disappeared. Now it's only a square-ish shape. I previously had names in the chats, so I'm not sure why it changed. Their names still appear in their video on the main screen. I use this for tutoring, so I need to know which kids are typing which words.

Thanks!

Bear with me as I'm Deaf so English / Explaining what i'm trying to do 

Basically what I'm trying to do is disable the pop up but merge my camera into gallery view 

as you can see from the image, my camera is on the top left corner and i want it to be in the Gallery so that its easy to see myself while talking to multiple Deaf users 

I hope i make sense? 

When I create a meeting, people and myself are obligated to connect with a phone. Even if the speakers and the mic is selected in the settings and the tests are working.

My speaker and mic work if I am invited into someone else's meeting. 

This problem persists even If I use my collegues computers so it seems linked to my account.

Mic permissions is enabled in windows 10.

In my Zoom account settings, I set that Computer Audio is to be connected automatically. It does not work. When my meeting starts, a windows pops up with all the phone number available to connect by phone.

Hi I've searched past questions/ discussions but not found anything quite the same. 
When I use my Zoom pro account, the content in the chat box remains the same/ visible to all when they are in the main rooms and breakout rooms. I can also message people when I'm in the main room and they are in breakout rooms and they can message me.
I am now doing some training with an organization. In the trial run Zoom session we just had, using their account, people in the breakout rooms could message everyone but no-one in the main room or other rooms saw the message. I could be in the main room messaging everyone but no-one in the breakout rooms sees the message. Then when we all came back to the main room, some of the content that had been in the chat had disappeared - specifically file attachments. We would like to keep the content in the chat if possible. 
I've looked at meeting room basic and advanced settings and not seen anything that quite fixes this. 
Any thoughts, anyone?
Much appreciated
