Was using this on the switch 2 for several hours. As I tried to hone in my macro, it suddenly stopped connecting to my switch 2! This is on the PC/Vagrant setup. Bluetoothctl list shows Pro Controller. Bluetoothctl devices doesn't list the switch at all, neither does it pick it up with scan. I had to start my connection each time via the change grip/order screen before it stopped.
I went into the switch settings and cleared all the connected controllers, no avail.
