Shell ItemTemplate and MenuItemTemplate are not applied dynamically at runtime

[NafeelaNazhir]

Description

When updating the Shell.ItemTemplate and Shell.MenuItemTemplate dynamically at runtime using code-behind (or binding via ViewModel), the new templates are not reflected in the Shell Flyout.

Actual Output:

Screen.Recording.2025-11-06.at.11.56.44.AM.mov

Steps to Reproduce

1. Run the attached sample : TemplateIssue 3.zip
2. Tap the button and observe that the templates are not updated.

Expected Result:

• After clicking the button, the Shell Flyout should immediately update and render the new templates. Both ItemTemplate and MenuItemTemplate visuals should change accordingly.

Actual Result:

• The Flyout does not reflect the new ItemTemplate or MenuItemTemplate. The old templates remain visible, and the new templates are not applied.
