I am facing an issue with the background image of one of my elements. The image loads perfectly on most devices such as iPhone 5, iPhone 5c, and Samsung Galaxy, but it does not load on iPhone 6, iPhone 6 Plus, and some iPads. Can anyone provide insights into why this might be happening?
.content-block {
background-image: url('image/img.jpg');
background-size: cover;
background-repeat: no-repeat !important;
background-position: center center;
min-height: 500px;
margin-bottom: 50px;
}
