Before the Update to the latest DruPal 8, we were able to link to
public://foo/bar.pdf to a file which was in
/sites/default/files/. No the
public:// prefix does not work anymore in the URL input field.
We are still able to enter the full link, but this might have the downside that it needs to be updated when the file name changes.
We also tried
/media/1337 but it shows a new page with the download link, while we need a direct download.
Can this still be accomplished?
