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
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.
