The Bluetooth on my Surface Pro (5th Gen) has not been working properly since the Surface Firmware Updates this morning. I have to restart to get it to work and then it only works properly for about 5 minutes. I have tried rolling back and reinstalling the Marvell driver. Also the Bluetooth troubleshooter doesn’t fix it. Running that troubleshooter causes Bluetooth to completely stop working. Will you please fix this urgently as it is a major issue for me?
