Мобильная версияЯ читал различные ответы и официальную документацию Firebase о том, как связать несколько поставщики аутентификации, использующие linkWithCredential, и пытались реализовать его в своем коде, но всегда терпели неудачу, показывая ошибку, что этот адрес электронной почты уже используется другой учетной записью.
Я не мог понять, где мне нужно разместить метод linkWithCredential.
Пожалуйста, подскажите, я прилагаю код для двух действий.
