Webcam quality bad on Teams desktop but good on Team web
Same issue here, using both a Logitech Meetup and PolyR30 for testing.
In their own respective apps (I.e. Poly Lens) - quality is perfect (arguably just a local video source so perhaps not a fair test to exclude network)
In Zoom Windows App, both camera's offer pretty good quality
In MS Teams web, both camera's offer pretty good quality
In MS Teams Windows App, both provide poor video quality
Already cleared cache and am on current Oct release of MS Teams.
Just as an update, I later found when logging into the MS Teams app using an account from a different tenant, quality seemed substantially better. Weirdly when then logging back in with the account from the original tenant quality remained good.
So, a bit unclear on how the local Teams app checks and downgrades quality if required, as none of the tests in the Microsoft testing portal would have indicated a problem.
One thing that was helpful was checking the resolution provided in the call|advanced|other settings as there were some occasions where screen resolution of both parties was good but it was in fact the video quality of the call being poor due to lighting conditions and not the call. (This was not the original problem though!)
