I was looking forward to trying it but the first thing it did was ask for my email. I would have liked if it let me at least try it without having to enter my email. Anyway, reluctantly, I entered my email but then I never received the access code.

I think you have a pretty big hurdle in the sign up and might be losing customers because of this. I would suggest allowing users to at least try it without signing up and also provide "Signup with Apple" instead of email.
