Hi Joseph,
That is interesting! Are you using these with RetroPie or similar?
If you get into the terminal (hit F4 and type bluetoothctl paired-devices
what do you see? Could it be a MAC address conflict or something like that? Or perhaps just your OS not telling the controllers which is 1 or 2.
Does this behavior occur when connected via USB too? Or just bluetooth?
Keen to get to the bottom of this one!
