Current behavior: Markers appear on screen and then disappear. They reapear after moving or zooming. I'm using markers and marker clusters. Tested on an iPhone 7 and an iPad Mini 4

Expected behavior: Markers should not disappear. Works fine on android.

Related code, data or error log (please format your code or data): I cannot post the full project, but the relevant part is:

var map = new google.maps.Map(document.getElementById('mapStations'), {
    center: {
        lat: -33.4427816,
        lng: -70.6400344
    },
    zoom: 14,
    disableDefaultUI: true
});

var estaciones = [ /* data goes here, around 650/700 items */];

var markers = estaciones.map(function(estacion, i) {
    return {
        'position': {
            'lat': estacion.lat,
            'lng': estacion.lng
        },
        'icon': {
            'url': 'img/pin-copec-solo.png'
        }
    };
});

var markerCluster = map.addMarkerCluster({
    'boundsDraw': false,
    'markers': markers,
    icons: [
        {min: 25, url: "./img/markercluster/blue.png", anchor: {x: 16, y: 16}}
    ]
});

This issue only manifest on iOS. Thanks in advance for any info.
