When screen sharing people see black screen
Hi Viren_Manek;
Believe is ISP related.
Change the QoS setting in Teams fixed the problems for us.
Your tenant admin needs to change this:
Teams Admin> Meetings > Meeting Settings > Network
Turn off -> Insert Quality of Service (QoS) markers for real-time media traffic
Also update Teams client to the latest version.
Log-out and log back in.
Restart your Teams app.
You may need to wait for the change to kick in.
Good luck.
Regards
Tenny

Hi ThereseSolimeno,
I have tried the first 2 options but not the third one. Will try that.
In meanwhile, I found that when I use teams via web browser there are no issues and works fine. So, the issues is more likely with the installed app.
Thanks and Regards,
Viren
- Yes that often happens. The tech support team is trained to ask whether the issue shows up on the web as well as the app.
- One question, I remember checking on the 1st link you provided before and it says that login to "Admin Centre". When I tried that link, it says that I do not have access....
How can I get further on that solution?
