Horizontal handle Drag is not working in mobile

[gowdruNikhil]

i have used this slider for a control but when i check the same in iPhone its not moving (range slider handle) but the functionality is working fine.

below is the code sample
<Slider value={volumeHorizontal} orientation="horizontal" onChange={this.handleOnChangeHorizontal} tooltip={true} onChangeComplete={this.handleChangeComplete} />

fix the issue or help me to fix it asap.

thank you
