my application is using the Touch API to detect touch events in JavaScript. Example:
$(\".element\").on(\"touchstart\", function(event){
alert(\"TRUE\");
Try using the pointerdown event. Some (much) more information. As you can see, touchstart is triggered by Edge but not in all configurations, when a keyboard is attached/paired for example, no touchstart.
Did you enable custom touch handling ? You can do it with the following css snippet (on the body tag or just a container for geastures) :
-ms-touch-action: none;
Next, touch API is a webkit feature (maybe there is an error in CanIuse ?). IE and Edge have a similar feature known as Pointer API. But you can use a polyfill library like this : https://github.com/CamHenlin/TouchPolyfill
for touch API, you have to activate a flag on Edge : in the address bar, enter about:flags and press enter. In the section Touch, you can enable touch events with the corresponding dropdown
