Уведомления FCM не получаются в приложении, загруженном из playstore, но отладочная версия работает нормально?

Question

Я недавно опубликовал приложение в игровом магазине. Он не получал push-уведомление fcm (при условии, что я использую канал по умолчанию в консоли fcm), но получал тестовое уведомление fcm на то же устройство.

Отладочная версия приложения получала уведомления fcm нормально, а также получала fcmТестовые уведомления обычно.

Пожалуйста, исправьте любые изменения в коде!

Заранее спасибо!
