J'ai un problème avec plusieurs compteurs à rebours et vue de recyclage. Quand j'ajoute une nouvelle minuterie, la précédente s'arrête. Et puis cela fonctionne très étrange, quand les secondes sont les mêmes, beaucoup de minuteurs peuvent travailler en même temps. J'ai beaucoup cherché mais je n'ai pas trouvé de solution à mon problème. Aidez-moi s'il vous plaîtcompte à rebours multiples vue recycleur
