Is this a duplicate of #10310

This is not limited to AppThemeBinding, I'm use the DynamicResource model and have the same issue except I never see the RequestedThemeChangedEvent.

If anyone else is see this, I've put together a workaround at https://github.com/DanTravison/ThemeSelector.

This will be fixed in #11200

[HobDev]

@mattleibow when this will be available on stable channel

[scriptBoris]

@mattleibow Yes, and how to update MAUI to the version where this fix will be fixed? If in Xamarin.Forms it was necessary to update nuget packages, but in MAUI???
