Good news! Worklogs - Time Tracking and Reports team has just released a new version, and since you use Jira Server you can decide to upgrade at any time! All that is needed is a click of a button in the Apps management screen on your instance!
Improvements:
We have relocated options from the dropdown menu to the drawer on Worklogs page to optimize user interaction by providing a more organized interface for accessing application functionalities.
We have added functionality for managing totals visibility. This enhancement enables users to better tailor the displayed data to their specific needs.
Bug fixes:
Fixed a bug that didn’t allow saving more than a few reports with multiple users or groups selected.
