I'm trying to remove our initial admin user before my trial expires, so we don't need to pay for it. I started by removing them from the Org Admin. Don't worry, I made sure we had another Org Admin first. Then, I revoked site access.
Now, I want to remove them from site-admin, then delete them as a user.
Their user profile shows they are a part of the site-admins group. I try to remove them from that page from the "..." menu, but I get the error, "Had trouble removing user from site-admin group." The site-admin group page does not show the user as a member.
What do I need to do?
