Cloud and Business ID_File Sharing is not possible

Hallo Everyone,

i have an Issue with my Creative Cloud.

I have a Business account and i want to share with my team files , but it does not work.

I already called the Adobe Center and i already have been on this link https://helpx.adobe.com/de/creative-cloud/help/collaboration.html.

So i know how to share but from business to personal or from business to team it does  not work.

Can you help me please?
