Hi!

I cannot get Phases Timing for EUM for XHR Requests. It says nothing spent on server side and No detailed timings available - "Timing-Allow-Origin" header not set.

Here are some screenshots

W3C timing

Any ideas why it can happens?

If the XHR is a cross domain XHR, then the browser will give you timing information only if this response header is set: https://www.w3.org/TR/resource-timing-1/#timing-al...
Facebook for example sets this header.

Thanks. Do you know how to fix it in easyTravel demo?
