I need to restrict users to certain organizations only. However, I've run into issues with the standard "Assign organizations" function. If I add companies using this functionality, and the user is still in the role System User, they can see all companies, not just those I tried to restrict them to. If I take the user out of the System User role, they can only see the company set up as their default, regardless of what extra companies I added to their user and roles.
Has anyone encountered this? Is there a solution? It is extremely urgent that I resolve this, any help would be greatly appreciated.
