Я хочу попробовать нанести несколько разных пешеходных зон на карту, используя полилинии. Приложение отлично работает для одного, однако, когда я пытаюсь добавить пешеходную зону 2, полиин вообще не отображается между точками зоны 2. Как я могу получить это, чтобы показать полилинию для зоны 1 и зоны 2?
Я не могу понять, где я ошибаюсь с этим, так как он отлично работает для первой зоны ходьбы, но не когда я добавляю в дополнительной зоне.
