What controller are you using with the Deck?
My pick after searching around is the 8BitDo Ultimate C (link) which is the cheaper version of the ultimate with no dock. So far, it’s been working well for me. I just had to restart the Deck the first time after the pairing, since then, it recognize the device all the time.

They work flawlessly on the deck. I snagged one on sale for 40 usd.
