I would suggest that all users should have read access to projects upfront (title, tags, project creator & project description) with the further ability to submit a request to the project creator to share the report.
Potentially add in a Browse All Projects button next to the Create Project button? Then when a user lands on the All Projects page they see what projects are available but cant access the project itself. The user should then have the ability to request access to the project from the project creator to then approve/decline.
This will streamline the process of sharing projects and democratizing data.
At the moment seeing all the projects is not intuitive and as such half the time you don't know where, who or what projects have been created until they are shared with you. It creates further complexity where you need to then send an email outside of Adobe to request the project creator to share the report with you as a user.
