Hi, you can use Auth plugins with any plan. But for now you cannot use our built-in roles system to restrict the access to a page without an higher plan yes.
That said, since the summer update you can easily do it yourself through a workflow on page load, you can check the roles of your user and redirect him to another page if he doesn’t has the permission to access it.
Your issue could be you still have one page with a role access rule, check if all your pages are public or authenticated, some may be bugged, you can try to turn them public and private again so it will clear possible invisible roles.
If you still have the issue please open a ticket on support.weweb.io and we will help you
