Same issue for me - we use the Yealink UVC30 4k cameras and they consistently default back to a wide FOV - in the "classic Teams" you could adjust pan/tilt/zoom - now there is nothing.
Did anyone actually get to the bottom of why this has been removed in "new Teams"?

I work for an S&P500 M365 customer. After reporting, I was told that Microsoft's engineers are aware of it and looking into fixing it.
As for why the feature was removed, my guess is since it's an ffmpeg feature there may have been licensing or packaging challenge. 1 of the major reasons for new Teams was a lighter client, and I suppose shipping the entire ffmpeg library - if that's what they did previously - wasn't in line with that.
If you're an IT admin you might be able to push ffmpeg and a matching .bat file to users who want the feature back, and then possibly remove it after the feature has been reinstated.
