After updating a some HP Conferencing units to Teams Rooms 4.19.57.0, I get an error:
"Microsoft Teams Room device isn't certified.
You must insert the HDMI adaptor that came with this device. If you continue to have problems, contact your organisation's admin or IT support desk."
These systems worked perfectly well on the 4.18 versions.
I have tried with & without the HDMI adaptor.
Is there a way to downgrade Teams Rooms versions at all? I've tried "Reset this PC" multiple times but it only seems to re-install the 4.19 version.

Good Day,
I have the issue now with multiple devices. ( Intel, yealink etc.).
''Microsoft Teams Room device isn't certiefied.'' I have multiple Intel Nuc ( Rev 2, 3), and yealink devices that are not certified. What is the best way to solve this issue?
Yes, I have same issue with that error message but after update GC8 driver that error not happen again.
Has anyone seen this issue since installing the latest 4.19.82.0 update? "Other bug fixes and improvements" is listed in the release notes so i'm wondering if this issue is one of the bugs.
Darn, I was loading on a Surface which is a touch device and I'm still having the problem. Might try again with a micro form factor machine I've got here and round up a different touch panel. Thanks
Can you tell me how you got past the error/restart and logged into the computer?
