Huddlecam Simpltrack 2 Compatibility

Hi,

I just installed a Huddlecam Simpltrack 2 web cam.  When I open Zoom for a meeting, the image I transmit is VERY grainey and out of focus - basically unusable.  If I open Zoom Video Settings and select HD, the problem goes away.  However, I understand Zoom does not want everyone to select HD in Video settings.  Has anyone else run into this problem, and if so, how did you solve it other than selecting HD.  Thank you.
