The end-user can switch slides in a CLM Presentation by using a mouse. However, the end-user cannot switch the same slides when using the touch-enabled device.
Add the following code to the relevant js file.
var touch = ('ontouchstart' in window) ? 'touchstart click' : 'mousedown';
var touch = ('ontouchstart' in window) ? 'touchstart mousedown' : 'mousedown';
