Yes my problem is solved by making my widgets Focusable again. This option is in the root of the widget. Then go to the details pane and under the tab “Interaction” check the box: “Is Focusable”. My UI works by calling setKeyboardFocus when a page is loaded. The page itself than intercepts the OnFocusReceived and sets the KeyboardFocus to its first button. So then every time a page is shown, you can navigate it with the keyboard. But since the page did not receive focus any more, nothing received focus and keyboard navigation did not work.
