I think this is correct. I followed your link and my “Activation (is) in Progress”. I will get an email when it is created. Thanks. I will mark your answer correct when I get it. Already upvoted.
@Eddie , Typically it takes 2 - 5 minutes. If it didn’t work for you. Keep us posted. It might have failed sometimes due to ongoing issue with ldap & trial org provisioning. If you still see the issue, Let us know, We will provision new trial org for you.
