My chime lost it's pairing with the KD110 and won't ring when the doorbell is pressed. I have tried re-pairing it using the steps in the FAQ, moved the chime closer to the bell, cheched DND is disabled, pressed the Pair button until the green LED blinks and tried pairing again. Nothing works!

The doorbell is working fine and sending notifications and showing events etc. but the chime does not ring when the bell is pressed.
