Is the switch hard reset working properly (hold for 20s until red, blinks red, green, blue, then comes back on blue?). I’ve never had a hard reset fail me but might be worth trying again.

I held the config button and it cycled green, then yellow, then red, at which point I released the config button. I was following the instructions here under “Factory Reset.”
