Just tested it and worked fine.
May you tell me which country you used to see if that could be the issue? If still interested, you may try again. Thanks for your interest!
Australia and with a dot CH email address.
Just tried again with this dummie address “ alan.h@aba.ch” and Australia and worked fine. Have you tried again?
Plus we’ve had more signups since you posted this so I’m guessing it might be on your end or possibly a typo on your email address…?
