Platform for XIAO nRF54L15 Zephyr Support fails to install

Have you managed to get any other apps working on any other NRF devices? Or is this issue only applicable to the new NRF54L15?

I built a Zigbee Light Bulb (XIAO NRF52840) and it doesn’t work - build etc, has CLI but fails to join my Home Assistant network.

I’m looking for someone who has built these applications and has them working.
