All submittals are private by default and visible only to the people on them. A Project Editor can make a submittal public so all members of the team can see the submittal, ensuring that the team only sees necessary submittals.
A Project Editor can make a single submittal or multiple submittals public to the team at a time. They can also make individual or multiple submittals private if they need to hide them from the project team.
When a submittal is in draft state, it is only visible to the issuer, reviewer, and project editors, regardless of the visibility setting. When a submittal is closed, it is visible to the project team, regardless of the previous visibility setting. You can change the visibility back to private, if needed.
