I can pair the Assault AirRunner, but no speed is transmitted. About six months ago everything was still working perfectly. The only solution at the moment is to use the companion app. (Windows 11, Bluetooth)
Hi Kesi,
I´ve got the same issue. Do you already have a fix or solution to this problem?
Hi Tim,
haven’t tried it again under Windows 11 since then. My “solution” is the AppleTV, which I only use for runs.
Too bad. 
But thank you very much for your reply.
Kind regards, Tim
