If a report has been shared with a group of users, what would be the best way to add new users?

Sharing the report with the new users directly is the most efficient and straightforward method. This approach allows the new users to gain immediate access to the report without necessitating any changes to the existing user list or the sharing settings of the report.

When adding new users, it's important to maintain the accessibility of the report for existing users, so simply sharing the report with newcomers keeps the process streamlined. This method avoids potential disruptions in access for current users and eliminates the complexity of having to alter the sharing settings repeatedly.

In contrast, manually informing new users or notifying existing users to add them can lead to delays in access. Unsharing the report from all users would cause unnecessary disruption for those who already have access and would require extra steps to get everyone back in the loop. Therefore, simply sharing the report with new users is the most effective solution for swiftly updating access while maintaining continuity for existing users.
