What Changed
By default, the Popup is now centered both horizontally and vertically on the screen. Previously, the Popup was displayed at the top of the screen.
Reasons for Change
We wanted to enhance user experience with the Popup component on desktop and mobile devices. In most scenarios, users are focused on the center part of the screen. The new Popup position is more convenient for enlarged mobile devices - Popup elements are immediately available for user manipulations, and users do not need to move the screen down to access these elements.
How to Update Existing Apps
Use the newly introduced HorizontalAlignment and VerticalAlignment properties.
