If this was mine I'd remove this device, it's apps and treat it like I was adding it for the first time.
I have a windows 10 pc and I have a mouse and Bluetooth headset that I use with it. I have media controls for skipping tracks on both and they both worked fine for a while. Then they suddenly stopped working. For a while resetting the human interface device service would make them work again. However now it only works at random times or whenever I have the task manager pulled up or the services tab. I have used both the mouse and the headset on another device and they both work flawlessly. Does anyone have any suggestions for what I should do?
