We would like to link a PDF with feedback directly in the user report so that students can find it quickly.

On https://moodle.org/mod/forum/discuss.php?d=450923 they gave us the advice to add the pdf in the feedback of the quiz. We tried to add it there. We see the text box where we can type the feedback. But we can't add a PDF.

• In ATTO we can only create a link. We do not have the option to upload a PDF specifically for the student.
• In Tiny MCE same problem: we see the Browse repositories button. But nothing happens when we click it.

We tested this on our own Moodle system. But also on http://qa.moodledemo.net

In the sandbox of Moodle 4.1 and 4.2. Also on these systems we're unable to upload a PDF. For the reasons mentionned above.
