In my issue details, I opened the Images/Source Maps Loaded section, and I'm seeing some files with status "Unreferenced" there. What does it mean?

"Unreferenced" means that the file was not needed to process this event's stack trace. If you are getting readable stack traces, then everything is in order.

If you are not getting readable stack traces, please ensure that you are following our documentation, and write to support if you are still getting stuck.
