Sharing HAR Files

Because HAR files can sometimes exceed the maximum attachment size limit (25 MB) in our Zendesk Support portal, we recommend uploading the file to a cloud storage service such as Google Drive, Microsoft OneDrive, or another large file-sharing platform. Once uploaded, share the download link within your support ticket.
