MAIN,INSIDE,SEAT,FOOD,WAIT
Я пробовал много разных способов, но когда я нажимаю кнопку завершения в действии ожидания, время не отображается. перезагрузить. Я хочу, чтобы часы в режимах «Место», «Еда», «Ожидание» работали как те же часы, когда возвращаемся или продолжаем, часы по-прежнему работают правильно. При нажатии кнопки «Готово» или при возвращении из места в салон часы необходимо сбросить. Например, если пользователь выйдет из приложения во время бронирования билета, время будет стерто и вернется к 10 минутам.

Я пробовал много разных способов, но когда я нажимаю кнопку завершения в действии ожидания, время не отображается. перезагрузить.  Я хочу, чтобы часы в режимах «Место», «Еда», «Ожидание» работали как те же часы, когда возвращаемся или продолжаем, часы по-прежнему работают правильно. При нажатии кнопки «Готово» или при возвращении из места в салон часы необходимо сбросить. Например, если пользователь выйдет из приложения во время бронирования билета, время будет стерто и вернется к 10 минутам.
