Already contacted them and they said they started investigation to see
how to make work Companion API. I suppose it will require an OS update
if they manage to solve it. Will update you when I get some news!
I launched a native Android app using CompanionDeviceManager working on
mobile on Quest and it doesn't work at all. So no more possibility to
work with BLE devices. What is not normal is that existing apps continue
to use location permissions!
