Thank you for your reply.
Yes, it was still a problem until 2 days ago and nothing seemed to help.
I've already tried the method you suggested before, too (you can see I did all that I can possibly do on my end).
But out of nowhere, the app seemed to recognize my device again yesterday, and I don't know what triggered it.
As you can see in the provided screenshots, there were no recent update since 10/23, which is the day I reinstalled Win11 using Barb's suggestion.
And I can assure you I checked the app 2 days ago and it still wasn't recognizing my Surface Pro 8.
Honestly, it still boggles my mind but it works now (somehow) and displays the correct information.
Maybe it's the server-side?
But thank you all anyways!
