Yes, I have heard from them. Long story made short, the August Windows Update broke the BT radio adapter and Microsoft says it cannot be fixed. It's affecting you, me, and thousands of fellow Surface users around the globe. If you go to earlier posts in this thread you can read the entire sad tale.
In my case, my Surface Book 2 is out of warranty. So the remedy for me is to send them the machine along with $599 and they will send me an exact replica of my broken unit that they promise will work just fine.
Unfortunately, I do not believe them. A Marvell AVASTAR BT Radio Adapter, integral to my broken computer and also to a replacement machine, is not a dependable component as far as I am concerned. If it broke once, it will break again. A waste of a good $599.
So I showed them. I just spent almost four times as much and bought a 2021 iPad Pro. It's arriving Friday. It will be nice to have a device that works. No, it's not a laptop but Apple has been very customer-oriented with me and my wife in issues that have popped up with our Apple devices.
The latest example: this spring I installed the beta of iOS 14.5 so I could unlock my phone via my watch while wearing a mask. When the gold version of 14.5 rolled out and I tried to install it, it bricked my iPhone XS. Fortunately for me, I had a trip scheduled to a city with an Apple Store. I visited the store. They thought they could fix it but they couldn't. My XS was out of warranty. Sound familiar? Well, they ended up giving me a brand new iPhone XS, and a high-capacity charger just for good measure. GAVE it to me. And much to my further delight, it came with a year of free Apple TV+.
You may say, well, you caused your own problem by installing the beta. Maybe I did. But the people at that Apple Store took full accountability anyway, and did right by me. Beats the five across the chops that I got from Microsoft.
My long story made short was not so short, sorry about that.
