Yes this is what I used. The bot asked a few questions and when I said all of them didn't work, it says "ok you can connect to a person below". Then I was sent to a chat channel. When they again gave some generic tips about how to troubleshoot bluetooth, I was sent to "experts" where I waited for an hour before giving up. I was in line 17 all the way to 3 and then never advanced.
At this point I've pretty much given up too. The adapter worked, and there's no hope this thing gets resolved before the return window is closed (I'm pretty sure it's a drive/config file updating thing), so I'll just go on using the adapter. The silverlining is the next time MS decides to release another controller that again doesn't work with Windows, at least I already have the adapter 😂
Thank you so much for helping me along the way.
