Я ожидал проложить маршрут между двумя точками моего текущего местоположения и другой точкой, но карта Google вообще не загружается. У меня есть API карт Google, включен API направлений и API карт Google, но я не включил биллинг, может ли это быть причиной того, что
код работает отлично, но не делает того, что должен делать
