How to generate a HAR file
When an issue is more complex it can be helpful for us to better understand what is happening in your browser while the issue is happening. Generating a HAR file from your browser that contains additional information about network requests can be very helpful to find the root cause of an issue.
Because HAR files contain sensitive data this should only be necessary if other methods of problem solving were not successful.
