I have added the user/s to the Permissions Edit field in the Plan access for Plan A. When the user looks for the plan, they can see it. Other plans (B & C) appear in the list as read only.
So far so good.
However, when they open plan A that they have been given edit access to, it shows as read-only.
They are NOT part of the group that has global permissions for Advanced Roadmaps, because I want them to have access to a single plan only.
How should I be setting up the permissions so they have edit rights to Plan a?
