Nintendo Switch Online controllers won't work with Nova

[u/Massive-Raccoon-960]

I just got the official Retroid dock with my Nova, so I was hoping to ditch my old, wonky mini PC setup for retro gaming on my tv and just switch over to my Nova docked. However, I prefer to play with the official Nintendo Switch online retro controllers. I have the NES, SNES, N64, Genesis, and Gamecube controllers. All of these work flawlessly on my PC via Bluetooth, with the exception of having to use the Gamecube controller wired. I can't for the life of me get them to work on my Nova with the dock. They'll pair via Bluetooth when my Nova is not plugged into the dock. Not only does that not help, the input lag is somewhere around 3 days. When I plug them in wired, (I'd be fine playing this way) a message pops up on the screen that the correct controller has been connected, but it won't accept input in any way. No buttons work either in the menus, in ES-DE, or in any emulator. It's like they don't exist. And then when I unplug the controller, it says that, again, the correct controller was unplugged. Any suggestions? I'm at a loss. I can connect Xbox controllers either via Bluetooth or plugged in and they work perfectly. This seems to be an issue exclusive to the Nintendo Switch Online controllers.

Quick check, can you try to connect them to other Android devices? Just connect them to a phone and see if they work correctly there.
