Who can view form responses?

Who can view form responses?

We are a small company.

I am the super admin and have a few forms.
I wanted to give another employee access to view/edit entries/responses on one form, so I added him as a user and changed the form ownership to him.
Now I can't view/edit the responses, only he can??  I feel like the super admin should be able to view the responses on any form - is this possible and i'm just missing something or what?

Thanks.

PS
The help site should explain what form ownership means & allows more clearly - I keep seeing how to change it but not anything else
