Dear Hania.
There is no answer for this yet, not in any forum thread is there a solution to the issue, just people wondering about when Microsoft is going to handle this and release a update that makes the settings available again.
I think worst is that the default for the user often is a blurred "soft focus" and you can not change it to higher quality which makes video calls right now impossible due to bad video feeling.
I have tried a little since I have ap 100 different clients on Mac running in our Enterpirse environment; it feels like it's worst at "MacBook Pro 14" M1", much better default on MacBook Air M1 and M2 as well.
MacBook Pro 16" M1 is actually quite good when using Teams through browser but still no settings available anywhere.
It doesen't matter what version of Teams app your running, seems to be the same issue everywhere, no settings and default is not very good.
If you need us to try something, please just answer and I'll try to help you making it possible to develop a future solution supporting even Mac-computers camera-device. ;-)
Thank you.
Kind regards
Sanna
