I do not know if it is a bug or a missunderstanding on my side but the XMLHttpRequest progress event doesn’t seem to work on iOS preview.

If I execute the following code on Local preview, all events are firing. On iOS preview, all events are firing except the `onprogress`

I am using Fuse version 0.30.0 on MacOS 10.12.1.

```auto
var oReq = new XMLHttpRequest();
oReq.open("GET", [URL_TO_FILE], true);
oReq.responseType = "arraybuffer";

console.log("Request created");

oReq.onloadstart = function (oEvent) {
	console.log("loadstart");
}
oReq.onload = function (oEvent) {
	console.log("onload");
};

oReq.onprogress = function(oEvent){
	console.log("progress");
};

oReq.onloadend = function (oEvent) {
	console.log("onloadend");
}

```

Thanks in advance for your help

Thanks. For your info, I just tested with a release build and it isn’t working as well. So the bug isn’t related to iOS preview only. Unfortunately no way to test it on android for now.

Thanks again for your support
