Creating HAR files for troubleshooting with Support

Troubleshooting UI / permission issues can prove difficult when Support don't see the same behaviour that you observe. An HTTP Archive (HAR) can often help here.

A HAR file is a JSON log of the web browser's HTTP interaction with a site. This can often expose errors that aren't otherwise displayed in the UI, or timescales that can demonstrate performance issues.

You can then attach and send the HAR file in your email to Support.
