Camera control greyed out on PolyTC8 when joining Teams meetings via Direct Guest Join on Zoom Rooms

Occasionally, I can't control the camera; the camera button is grayed out when I join a Teams meeting via my Poly G7500 device (set to Zoom Room provider mode).

I've tried restarting all the Poly G7500, Poly TC8, and Trio8800 devices, but this didn't fix the problem.

After a few hours, when I rejoin the Teams meeting, I can control the camera again, and the camera control button is no longer grayed out.
