If a user cannot see the Admin tab, what is one way to resolve this?

The correct response focuses on the solution of adding the user to another security role that possesses Administrator permissions. This approach is effective because it directly grants the user the necessary access rights to see the Admin tab.

When a user is assigned a role that does not include the permissions associated with the Admin tab, they will be unable to view it. By placing the user into a role that has these permissions, you ensure they can access administrative functions as needed.

In the context provided, other options may attempt to adjust settings or change roles, but only adding the user to a security role with explicit Administrator permissions guarantees access to the Admin tab. Adjustments to settings or permissions under the Default User role might still leave essential access rights missing, while switching to a custom role requires ensuring that the custom role has the necessary permissions set, which could be an indirect and less guaranteed method compared to directly assigning an appropriate role.
