I have a new Elite Series 2 Controller, and having issues with Bluetooth that randomly disconnects.
I can reproduce it by lauching WRC 8, at some point in the menu or in a race, the controller will get disconnected after a big stutter, and sometimes, it never reconnects (light is blinking on the controller, Windows says the controller is paired but will never see it connected even after restarting the controller, in this case, I have to remove the controller from Bluetooth device list and pair again).
The controller firmware is up to date, Windows 10 64 bits is up to date, the Bluetooth driver from my Z390 motherboard with Intel Bluetooth controller is up to date.
I have a regular Bluetooth XBox One X controller that works perfectly on the same host.
Also, we are multiple people to have the exact same issue:
