Почему не проходит верификация номера телефона firebase?

История такова, когда я работаю на прямую из Android Studio всё работает, но стоит мне создать apk файл, то верификация телефона просто не работает. Я взял проверку на квоту из документации. Но выводит ERROR на отработанную проверку ниже в коде. В чём проблема? У меня подозрение, на то что Google Сервисы не хотят сотрудничить с моим приложением, потому что когда я устанавливал приложение у меня вылетело окно Play Защиты, оно придупредило о не проверенном источнике.
