Hi Alex,
Thanks so much for your report!
The form usually does not work due to a wrong or missing SMTP configuration. This varies from hoster to hoster, so it is impossible to say in general what the reason is in your case. Have you ever tried using an SMTP plugin?
If that doesn’t work either, please send temporary login credentials and a link to this thread to help@bricksbuilder.io using the email address you used during the purchase.
Best regards,
