Trying to get navigation back button or search bar cancel button localized

Hi,

Our Forms application is running as expected in différant languages but, on iOS, we can't get the right localization strings for the back button in navigation bar or cancel button in the SearchBar. Setting a (localized) title on each navigated page is not a solution since the word "Back" may be used when the current page title is too wide.

Could you help on this point ?

    Thanks.
