What's new
Merci aux bêta-testeurs pour vos retours ! Cette mise à jour corrige : • Le défi du jour propose bien 15 questions (il en manquait une certains jours, ce qui faussait le score). • Le bouton retour ne bloque plus le quiz sur une question déjà répondue. • Le rang « OSI Master » s'obtient à 376 questions maîtrisées : il était jusqu'ici inatteignable. • Si vous aviez déjà tout maîtrisé, votre rang « OSI Master » vous est attribué à l'ouverture de l'app.
