Thank you very much for your response. 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.
According to https://tracker.moodle.org/browse/MDL-78189, PDF uploading has been fixed in Tiny MCE Moodle 4.1.5. So that can't be the problem. In the meantime, everywhere else in Moodle we can upload PDFs with Tiny MCE. But we can't upload pdf's in the test feedback.
Moreover, we cannot upload with Atto either, in the test feedback.
Thank you
