User did not receive the invitation link

I am the admin of the FREE akaunting account and can only enter 1 user. I assigned it to a non existing email and because of that, I cannot delete the user unless the email is true and should be verified to 'Get Started' the account. So what I did is to create that email. Now that the email is true, there was no invitation link sent in that email.

I tried clicking the "resend invitation" but there is another page with code on it.

How can I fix this? Hoping for some to assist.
