kotik morskoi (ID: 00000014a0b51951) Voted 4 ★ - Updated 03/20/2023 Работает. Интерфейс немного мутный, но если потыкать то что-то получится. Для платежных целей наверно не пригодится. Внезапно исчезает не сказав до свидания и приходится снова вызывать. Вылезает в центре экрана и не понятно как его переместить в сторону. Чтобы запустить нужно в правом верхнем углу браузера нажать на нечто серое типа ломаной шестеренки и в открывшемся окне нажать на иконку приложения. Откроется окно приложения и внизу в центре нужно нажать кнопку старт.
