M12 HD very good ergo but confusing with all its modes and no wake function at all.

I received my M12HD and it's pretty good in the hand. The joysticks are very smooth with just the right amount of resistance. The buttons are clicky but not loud - it feels great to press like the M6HD. HD rumble is pretty good too.

The modes of connection, either wired or wireless, are confusing. When you use the switch on the back to turn on the direct connection (switch in off state - I know it's confusing as hell), it is basically wired mode, and in this state, NFC will not work. I am not sure if this is because of the Switch 2 protocol—it probably is. I ended up using this mode when I dock my Switch 2 so it also charges the M12HD. I switch it back off—wireless mode—when I use it handheld so NFC works.

the thing that's confusing is that the switch still thinks it's connected to 2 separate Joy Cons when in wired mode. I was expecting it to see a wired pro controller. Maybe it's because it is connected to the rails and not the USB port? Not sure.

There is no wake function at all. I tried connecting it using the same method as the M6HD but it wouldn't wake the Switch 2 at all. Tried with wired mode as well and that also didn't work. In fact it was worse because the controller will also only wake up if the Switch is awake.

Hopefully, the new firmware with the needed features gets released soon. As it is right now the only thing that's good about the M12HD is its ergonomics, the smooth joysticks, and the HD rumble.
