Some of the buttons (power, vol up/down) work, but others like the navigation keys don't, no matter which code group I've tried. I was planning on using this with my Nvidia Shield 2019 through HDMI-CEC, but it doesn't respond either. There seems to be a Flipper Zero-compatible IR file for the C1 remote floating around, but I didn't want to go to the trouble of manually converting it to work with the Skip.
