Мне пришлось начать свой проект заново из-за этой проблемы.Когда я нажимаю на кнопку переключения, Карты увеличиваются и отображают карту серого цвета, которая не является местоположением.Я пытаюсь создать приложение Uber Like, и если я не могу пройти этот этап, я не могу двигаться дальше.Любой, кому нужна помощь, должен.

Решение, которое поможет мнепройти этот этап будет лучше, потому что у меня нет сил вернуться назад и начать все сначала
