Подтверждение по телефону Firebase

Question

Здравствуйте, я новичок в разработке студии android, и я следую инструкциям на YouTube. Я следую коду, но когда я запускаю приложение, проверка телефона не прошла. Я из Филиппин и в настоящее время использую код +63 на своем номере телефона, но он не прошел аутентификацию в базе данных firebase. Пожалуйста, помогите, и вот код ...
