About assignments

Hello Survey Solutions team,

I have a doubt, a user headquarters and a supervisor user can see the assignments made, if all the interviews of the assignment are approved by the headquarters, I can still visualize with the headquarters and supervisor users.
I think they should be filed and not shown to the supervising user because without having interviews available, the supervising user can reassign another interviewer user of his team and that assignment does not really have interviews available.

the supervisor has the assignment disappearing as soon as all the interviews on that assignment are approved by the supervisor.

the HQ user always sees everything.

I have this assignment which no longer has interviews available, but it still appears to the supervising user.
