Как мне правильно узнать, есть ли у пользователя дополнение подписки для моего приложения в магазине Microsoft? [закрыто ⇐ C#

[Anonymous]

У меня есть приложение в магазине Microsoft с дополнением подписки. Приложение бесплатно, и подписки требуются, когда зарегистрировано определенное количество людей. Мой код ниже должен представить диалоговое окно контента, информирующее пользователя о ситуации и, если они хотят подписаться, представить форму покупки магазина. Тем не менее, форма представлена ​​до появления диалогового окна контента. Что я делаю не так? Спасибо за помощь. < /P>
