When i set ActivationPolicy=\"Resume\" in WMAppManifest.xml page tile navigation(navigation URL) is not working in Tombstone state, it reloads the last back stack page(URL). It
Same problem here. I got WP8 application with Fast App Resume enabled. I can pin tiles pointing to specific pages in my apps. It works fine when app is just Suspended, but when the app is Tombstoned, then clicking secondary tile has the same effect as clicking the main tile.
I receive only one RootFrameNavigating event with NavigationMode == Back and Uri == /MainPage.xaml. The app then shows the previous page that was there before I suspended the app.
I guess this is actual bug in the platform for this specific scenario - Fast App Resume + tombstoned app + navigation from pinned tile, that we as developers cannot solve.
