iPad 1 displaying as desktop using Chrome

Using the simple:

if (MobileDTS::is('android')) {
    echo 'android';
} else if (MobileDTS::is('ios')) {
    echo 'ios';
} else if (MobileDTS::is('mobile')) {
    echo 'mobile';
} else {
    echo 'No';
}

I get No on my iPad 1 using Chrome, works in Safari… any fix for this?
