Hi @janus2 ,
Thanks for reaching out to us.
Fusion Team is the new design storage for Fusion 360 users. It has been the default storage for users who started using Fusion in the summer 2019 or later.
Fusion Team is a collaborative environment where you can store design data and work on your own or with collaborators. Whether you are the only member of your team or collaborating, you are always in control of your data and can define who can access it.
Here is an article explains how to start using Fusion Team and the benefits of the change. Though it's using Academia as the context, the idea should apply to you case.
