Так нельзя. Мне нужен тестовый период

Разработчик, ты теряешь деньги. Объясняю почему. Мне визуально зашло приложение, все круто.

Тут предлагают пройти тренировку и сразу оплата, но с предложением пробного периода в 14 дней.

И пробный период только, если только выберешь годовую подписку, а на счёте должно быть минимум 60 долларов. А с месячной подпиской такое не работает, тестовый режим не взять.

А так хотелось проверить приложение и скорее всего купить. Хотя бы на месяц

Response from developer

Пользователь 12levels: English Vocabulary, обращаем внимание, что у нас есть двухнедельный тестовый период. Видим, что в вашей стране еще есть возможность попадать в мировой интернет и оставлять единички даже на те сервисы, которые крутые и вам нравятся. У вас удалось подменить регион устройства на USA и пробраться в магазин приложений. Надеемся все же, что скоро этой возможности у вас не останется. Приложение рассчитано на другие страны. Для остальных адекватных пользователей — мы рады вас видеть у нас, приложение действительно крутое, и есть щедрый тестовый период для платного функционала.
