У меня есть простой реагирующий клиент для веб-сайта, на странице входа в него есть две опции: ввести код входа вручную или отсканировать его с помощью сканера штрих-кода. Я тестировал приложение на реальном устройстве, и эмулятор много раз работал нормально. На самом деле я тестирую только через ipv4, и для входа в систему я использую fetch, который, я думаю, поддерживает ipv6 по умолчанию.

Они говорят по сети ipv6, когда приложение было в автономном режиме, я не могу понять, что значит быть в автономном режиме и быть в сети IPV6?

Когда приложение находится в автономном режиме, я показываю пользователю ошибку, что нет подключения. так что я не знаю, как это может привести к сбою.

следует ли добавить тайм-аут для получения запроса исправить проблему?

Но приложение отклоняется 3 раза из-за той же ошибки:

Производительность - 2.1

Спасибо за ваше повторное представление.

Ваше приложение падает на iPhone под управлением iOS 9.3.3, подключенным к сети IPv6, когда мы:

В частности, нажатие на логин все еще приводит к сбою приложения.

Это произошло, когда ваше приложение использовалось:

Не в сетиПо Wi-Fi

Мы приложили подробные журналы сбоев, чтобы помочь устранить эту проблему.
