Ahh, thanks so much for that! Can I confirm the email you're using doesn't have any forbidden characters or blank spaces before/after the email, as well as a proper ending (".com")?
We'd definitely like to take a deeper look at this one for you, so we're having some chats internally to investigate further! We may also ask that you reach out via the Digital assistant so we can take this conversation elsewhere (if we need to request more specific details).
I will let you know what we find, and/or if we'd like you to raise a support request instead ☺️
