Hello Michael
Actually, there is not a perfect way to handle this requirement. You can try the options below:
1. Use this method to restrict access to the menu item which is created to link to CB profile, see
membershipprodoc.joomservices.com/resour...sing-joomla-core-acl
The idea is that when users subscribe for your plan, they will be assigned to Subscribers user group, thus having Subscribers access level. The menu item which you created to link to CB profile will have Subscribers access level, thus only subscribers can see that menu item to access to it
2. In the plan setting, there is a setting called Login Redirect , set it to the menu item you created above. By doing that, when subscribers of that plan login, they will be redirected to the CB profile page
Please try that and let us know if it works
