How can I see the forms my sub-users create?

They can see mine but I can't see theirs.  

The main account holder does not have access to the sub-users forms. Sub-users can use their own account normally, creating and editing their own forms without anyone else accessing them. But the forms created in the shared folder will belong to the main account holder so it can be accessed by them.

Please check the Guide on this:

Please let us know if you have other questions.

Thanks.
