Myron has an OwlCam and his LTE is still working. Leo says that he couldn't get his to work because OwlCam has closed down their service. So if it's still working now, it'll likely stop working soon. Maybe after his subscription runs out for the month.
Myron has also installed PopOS on his Thinkpad and it won't work. Leo says to turn off secure boot in the BIOS/Setup. It's designed to make sure you've installed a legitimate copy of Windows. Select F1 during boot up. Go to the security tab. Disable Secure Boot. That should fix it.
