Popup:

Calling

IsOpen = true,
IsOpen = false,
IsOpen = true,
IsOpen = false,

while the last IsOpen update isn't ready, kills the Popup.
It works async, even if animations are set to none/0s and there is no public event to validate the last update is fully done (Popup opened/closed)

In my case i have a popup opened, while a search operation is running in the background.
If this background search returns too fast and i set IsOpen to false, the update is ignored and the popup keeps in an opened state.

When the Popup control is attached to the page, the "Top" and "Bottom" options of the Placement property does not respect correctly.

If you have a modal Popup and update its PlacementTarget after IsModal is set, the Popup will not be shown correctly on Windows.

It would be nice to have more animation styles when the popup opens/closes.  Specifically, it would be nice to have an animation that slides in from a direction (top, bottom, right, left).  I would like to have a popup that appears to slide up from the bottom of the page when it opens and slides down when closing.  I know you can get a similar effect with the SideDrawer control but would prefer to use the popup.

Regression of the following issue: Pickers: [Android] Do not display in a Shell modal page in Net 9 project

The issue happens in Telerik MAUI 11.0.0, in 10.0.0 no issues

when having an input control in the popup, and open the popup. Focusing the input inside the popup displays the keyboard and this pushes up the popup off the screen.
