it seems people did not see one of my earlier posts here.
anyway this app that most of us have been using is through the UK Xbox page. The French, German, and Spanish pages all have the app as well. If codes have run out for the day, another option aside from waiting is to visit of the other app pages. simply add "fr", "de", or "es" after the slash.
for example the normal app usually ends with nothing after the "/" or "/uk"
try "/fr" "/de" or "/es" if you don't feel like waiting for codes to be readded.
