With the scheduled release upgrade, customers are able to add an announcement message for end users. However, some incidents caused by Atlassian may be beyond their control.
Therefore, the customers recommend us proactively adding a banner/ warning message to display at the top of the screen for users during rollback or deployment activities.

This feature would serve as a crucial alert for users, informing them of the potential risk of data loss during these processes. It would be especially helpful for users working over weekends, similar to the functionality provided in other products such as Jira.
