new Teams Group sharing on AVD

Having this issue currently, working with my VAR to find solutions. Not only screen sharing, but webcams are also impacted by this issue.

Fouad Chaar & Erik there is another topic on here (Teams showing blank boxes for shared content and camera images in meetings) where other partners had a similar issue and they were able to fix it by installing the March 2024 release of the WebRTC client (see https://nmmhelp.getnerdio.com/hc/en-us/community/posts/28915016868237/comments/29241760006925).

Have you tried that by chance?

I think this is suggesting an old version of the WebRTC redirector? I am afraid of doing that, because an older WebRTC had other issues...

Correct. The other partners found that by rolling-back to the March 2024 release, they weren't having the issue anymore.
There are other potential issues (that they fixed in the v1.54.2407... release), but it seems like the immediate problem with shared content/videos went away when they did that.

Not working still, unfortunately..

Here are screenshots from my freshly imaged host with your script running at provision-time. Always strange that Teams always says update available even when bootstrapped freshly :( . And video / screenshare works neither with this teams version nor after "update now" + relaunch. I will echo this on the other thread.

Hi Erik, it looks like the Teams bootstrapper installs 24180.205.2980.1757, which then auto updates to 24193.1805.3040.8975, which is the version I am showing in Teams now. This directory timestamps are very close:

Get-AppxPackage shows the older version:

I am going to try the Scripted Action tonight. I hope I have better results.
