Make sure to clear all layers of site cache, as well as the CDN cache. If something else might be conflicting, you can also try this custom CSS:

.asp_m {
    min-width: 500px;
}

@media only screen and (max-width: 768px) {
    .asp_m {
       min-width: 100%;
    }
}

If nothing works, then can you please share a URL where I can check this issue. Back-end details would be also nice, so I could check if everything is working correctly.
