Hi I'm in the UK: I've managed to get the colour demo working once but then it "sort of died". Service Simulator recognises it but neither the end-to-end simulator nor my Alexa recognises the skill at all any more.
Fundamentally, I'm unclear what I did that Service Simulator works and both the physical and simulated end point don't. I'm assuming I've got them both in a state that means it can't get out, but other skills still work.
Nothing useful in the logs: thoughts most welcome.
