Please expand about what icon you are talking about. It will not be clear to the
translator. Maybe say "...hovering over the application icon in a promotion to
install an application" or something like that.

Elaborate on what banner you are talking about, it will not be clear to the
translators what this is as it is not served together with other strings.
