Thanks for all the responses everyone. Seems like my issue might be related to battery voltage. When I'm getting low voltage notifications through fordpass, bed lighting doesn't work, so I'm guessing it's a circuit that is turned off or something when the battery gets too low.Long story short, if programming is good, check the wiring/terminals. Latest updates haven't impacted anything (wouldn't expect it to, but who knows).
Has worked fine plenty of times when I randomly push the button in the bed (even checked it today when unloading some stuff).
