2 of your specialists have asked me for a video now. A video. Please, explain to me, what is so unclear in "the mouse is not recognized in Windows' Dynamic Lighting section when connected via Bluetooth, even though it is recognized normally when connected by cable or by dongle", that you need a video? And a video of what exactly?
It's been literally a week (ticket was raised on January 18) and 7 (!!!) specialists and we have not moved an inch. Microsoft, maybe you can explain to them what they need to do to make the device be recognized in Dynamic Lighting over Bluetooth? Maybe you have some link for the developers or something (my googlefu did not find anything obvious)?
