I created some custom Q&As using the blueprint, and none of them work - when I ask a custom question I get the standard "Hmm, don't know" answer.
A possible indicator to the cause is that I get a warning message on the blueprints website:
"Your Amazon account is set to United Kingdom. To create skills that you can use on your Alexa-enabled devices, your country setting must match your Blueprints website. Please call Customer Service for assistance."
My Amazon account is indeed set to UK, and I live in the UK. My echo dot is here in the UK, and its registered address is my home (in the UK). However, I'm confused by the reference to the Blueprints website, as I can't find any country setting there at all.
Any help would be much appreciated!
