Hello, Lavenia A
Sorry to say that, but I think you may not get my question and key point, my problems is how can we pair with Surface Headphones 2+ through with new replacement "Surface USB Link" Dongle? it not my Surface Laptop problems, the problems is why the new Dongle can't recognize in Surface App. I have try to borrow the new one Surface Headphones 2+ and dongle form my friends and it can pair through original Dongle to pair with Surface Headphones 2+ in my Surface Laptop. (This will prove that is not my computers problem.)
Could you please help try this situation in Microsoft internally? or need you help highlight to your internal technical department for support? And this is not an isolated case, it seems that many people have the same situation in Microsoft community and also no get any fix solution.
Thank you!
