scroll - I get 2 fingers zoom on android but not on ios -

i struggling having 2 finger events on touch devices.finally removed meta tags html , made android device work , still have problem ipad.

i read other threads zoom in , tried different variation of meta tag :

    <meta name="viewport" content="     user-scalable=yes,     width=device-width,     initial-scale=1.0, maximum-scale=3.0, minimum-scale=0"/>

but none of them helped have scroll on ipad.

when have :

    <meta name="viewport" content="user-scalable=yes"  />

i zoom on android still no 2 finger pinch or scroll on ipad.

i appreciate or suggestion on that.
