Using the Milestone PATCH API, we update the Planner date by modifying the estimatedDate attribute. After this update, we can see that the change is reflected in the Planned Date. However, after some time, the Planned Date automatically reverts back to the Suggested Date.

We would like to understand:

• On what basis the Planned Date is recalculated or reset to the Suggested Date
• What system logic or rules trigger this recalculation
• At what time interval or frequency this action is performed
  Immediately after the API call, the update is reflected correctly in the Planned Date
  
  the Planned Date automatically changes back to the Suggested Date (after some time)
