-
Vérifiez la Configuration de l'Heure : Accédez aux paramètres de date et d'heure de vos appareils et assurez-vous qu'ils sont correctement configurés en fonction de votre fuseau horaire.
-
Redémarrez vos Appareils : Un simple redémarrage peut parfois résoudre les problèmes de synchronisation. Éteignez et rallumez vos appareils pour appliquer les modifications.
