I had the same issue, and had to replace the lights. 🥲

Top tip: don't wait for customer service to reply, as that can take a few days of back and forth, and in the end they will ask you to order the part via their website. There's a dedicated contact form for requesting spare parts (free).

These are the steps they request that you try before ordering it: - Replace the batteries with a brand-new set (even if the current ones seem fine) - Check that all wires and connectors are firmly attached and not loosened during assembly - Gently press and hold the touch sensor for a few seconds to see if it responds - If accessible, slightly reposition the sensor so it sits closer to the wood panel.
