Why can't I change my role to admin?

MASV users cannot change their own role. If you are a team Owner, you remain the team Owner unless you contact support@masv.io to permanently transfer ownership to someone else. Users with an Administrator role or a custom role that includes user management and/or role permissions, can assign a new role to other members of the team.

By design, there can be one and only one Owner of a MASV team. For more information about roles in MASV, see Roles and permissions in MASV.
