title_body: Taranis X9D Plus 2019: Switches SE,SF,SG,SH, and SI are not working/responding on Betaflight
upvoted_answer: The issue was on my Crossfire Nano receiver. I had to change the operation mode from 8 channel to 12 channel. Now switches from SE - SH work. Even though I defined all my knobs, switches, and button on my Taranis, I am limited to 12 channels from my crossfire nano receiver(4 channels for the sticks, 4 for front switchers, and 4 for top switches).
