Android app cannot see paired device (S21 Ultra)

I’m using Samsung S21 Ultra.
Successfully paired to Meshtastic device (T-Beam 1.2).
I cannot see the device in Android app.
Tried to change several AVRCP profiles, but without success.
Any help is appreciated.

if you are on firmware .45, make sure WiFi is disabled on the T-Beam.

Thanks for the quick response.
I have indeed configured Wifi.
How do I disable it via Python API?

set the parameters with empty values like: --set wifi_ssid "" --set wifi_password ""
