Invalid Mi 9 Miui12 Stable - Bluetooth unlock did not find devices

[vcdwelt]

Hi,
maybe a bug or something wrong with my device?!?
Rom: V12.0.2.0.QFACNXM_v12-10.zip

I have connected my Phone to BT Hanndsfree in car & BT Audio Adapter. Both working fine.
Now i tried to enable unlock via BT Device. I can open the dialog, enter my Pin, but there are no BT Devices listed, also search in this screen does not find anything. BT in genreral works great, i'm using several BT Devices without issues, but unlock did not show any BT Device, also tested with other Devices connected Also other unlock methods working great (Faceunlock, Fingerprint)

as far as I know, only the mi straps and some amazfit watches are suitable for the BT unlock. Not even the Mi Watch is possible for BT unlock

Oh strange.
But i'm really sure i used my cars BT in the past for unlocking. Maybe this was in Miui10 or 9 and has changed since.

MIUI uses a proprietary Bluetooth profile for unlock purposes, there is no way around it...

Ok thanks for feedback. Sad but true. At least i know the Reason now.
