I've reduced my request to just the default modules, I get confirmation on my browser that the request was accepted, I can't find anything gone to spam folders, and I've tried alternative email addresses that arrive via completely different email services. But still I get nothing. I've made numerous attempts over the last 2 days.
Is there any other stupid beginner's mistake I might be making? Anything else I can try? Or is my next step to do my own build?
