Battery life has been incredible since the first hiccup.
Bluetooth for the DT-903 doesn't work on 735 on this build. When I open gadgets, it never connects and the notification switch is greyed out.
none of my BT devices would open the app i had associated with gadgets while i had Windows Hello turned on. Its now off, and appears to work fine.
I know you dont have Hello, but do you have a PIN enabled? try disabling and see if it works.
