I'm sorry to hear that you're experiencing issues with signing up and receiving the email. Let's try to resolve this step by step:
1. Please check your email's spam or junk folder to ensure the email hasn't been mistakenly filtered there.
2. Verify that the email address entered is correct and there are no typos.
3. Ensure that your email inbox is not full and can receive new emails.
4. If the admin invite is not working, the admin should check if the invite was sent to the correct email address and if there are any restrictions that might prevent the invite from being sent.
If you've already checked these steps and the issue persists, please provide me with any error messages you're seeing or additional details so I can assist you further. If necessary, I can also help you get in touch with our support team for more in-depth troubleshooting.
