Microsoft Purview compliance portal: Ability to change retention period on labels set to start retention based on “When items were labeled”

items were labeled. This feature will remove this restriction, and the
resulting behavior will be consistent with other retention label types. GA date: February CY2024 อ้างอิงค์ : https://www.microsoft.com/microsoft-365/roadmap?id=153651
