Hey,
I just bought WMR Acer headset. The first time setting everything up went smoothly, and I was able to play around in the Mixer Reality Portal for around 20 minutes. Then both of the controllers disappeared.
After that I have tried restarting the computer, factory reset the controllers, replaced new batteries and re-paired them multiple times.
I can get them to add under "Mouse, Keyboard & Pen" and they show up as 'paired' but I cannot get them to actually connect / show up in MRP. I also tried this while changing the USB port used by the Bluetooth stick, to no results.
Any ideas?
