I had already had 2 webinars where the participants do not see the chat icon nor do they see that I have sent anything in it. I - as host - can see the chat icon and can send in messages. I have made sure that it says 'to everyone' and on the Zoom web portal I have also made sure that everything concerning the chat is on.
What else could be the problem here?

We are trying to  find a solution regarding how can a visually impaired person can access the content shared on screen using screen readers like NVDA or zoomtext or other screenreaders
Is there an already existing zoom feature for the same or any other solution.

Tengo un ASUS TUF Gaming F15 con GeForce GTX 1650. Soy docente, usualmente comparto la pantalla del navegador para mis clases. Sin mebargo, comenzó a aparecer ese mensaje incluso sobre las herramientas de zoom. Mis esudiantes ven un cuadro gris que crubre parte de la pantalla, equivalente a los controles de zoom. Y si abro, por ejemplo, el bloc de notas, ellos verán un recuadro gris sobre la parte de la pantalla en la que tengo abierta la aplicación. He intentando muchas soluciones que ofrecen online, pero ninguna funciona. Esto no me ocurría los primeros meses con mi computador.

I have an ASUS TUF Gaming F15 with GeForce GTX 1650. I am a teacher, and I usually share my browser screen for my classes. However, a message started appearing over the Zoom tools. My students see a gray box that covers part of the screen, corresponding to the Zoom controls. And if I open, for example, Notepad, they will see a gray box over the part of the screen where I have the application open. I have tried many solutions offered online, but none work. This did not happen during the first months with my computer.

We have a paid account.

I was providing a live training that some could not attend so we promised a recording of the training.  

At the start of the training Zoom Came On to say this session is being recorded and we clicked on "got it". 

I can only guess that we ran out of space during our live recording (which was 1.5 hours) and the recording or even part of it is no where to be found. HELP I cannot recreate this recording, it was live with 45 people.

Since 2 month, when I host a meating, I can't share my screen when participants came into the meating. They still can share their screen but I can't. It say that the screen sharing is unavailable. And when I look into my settings, everything is ok and everyone can share their screen.
