We have investigated the issue and managed to come up with a workaround for it. The following JavaScript snippet would fix it:


<script type="text/javascript">
    var $ = $telerik.$,
        $T = Telerik.Web.UI;
 
    $T.RadScheduler.prototype._onTimeSlotTouchEnd= function(e) {
        $(".rsContent", this._element).off("touchmove");
 
        this._onDocMouseUp(e);
 
        // If tapped on timeslot, select it
        if (this._timeSlotTapped) {
 
            this._onCellMouseDown(e);
             
            if (this._renderMode == $T.RenderMode.Mobile && this.get_selectedView() == $T.SchedulerViewType.MonthView) {
                var slot = this._activeModel.getTimeSlotFromDomElement(e.target);
                return this._switchToSelectedDay(slot.get_startTime());
            }
        }
    }
</script>

This fix would be available with the next internal build.
