Как решить: конечная точка принимает только запросы POST. Получен GET-запрос ⇐ Android

[Anonymous]

Я попробовал реализовать вход в Microsoft в приложении Flutter с Firebase. После входа в систему я получаю следующую ошибку: Конечная точка принимает только запросы POST. Получен запрос GET., но пользователь неправильно перенаправлен в мое приложение. При повторном открытии приложения я успешно вошел в систему.
Я использовал код:
main.file

Я настроил свой проект в соответствии с этой документацией:
Аутентификация с помощью Microsoft на Android
В то время как IOS и WEB работает хорошо, я получаю следующую ошибку при входе в систему на устройстве Android. При возвращении в приложение я успешно вхожу в систему. Единственное решение этой проблемы, которое я нашел, — это отключение параметра Блокировать сторонние файлы cookie и данные сайта. Я не хочу, чтобы всем моим пользователям приходилось это делать. Каким будет это взаимодействие с пользователем?
При добавлении следующего кода в мой манифест:
