Sharing folder contents gives error

I have a folder which contains several .mp4 files. I can share the individual files and using the share link they will play properly. However, if instead I share the folder, the contents are visible using the share but attempting to access a file results in:

The media could not be loaded, either because the server or network failed or because the format is not supported.

I am running containerized v 18.

Apparently this error occurs if the share specifies “Hide the Download”. Is there someplace else that this error should be reported to developers?
