I am trying to test GDPR in moodle master.

I logged in as student. I left few data here and there and then I went to my profile where I asked for "Data requests".

I submitted a new request asking to "Export all my personal data" and I log out.

As admin I received an email.

Then, after cron and always as admin, I found the request, I approved it and, after one more cron, I saw its status changing from "Approved" to "Processing".

Now it is 30 minutes it is processing.

Which bit am I missing? Where can I read about this process? Am I missing the DPO role?

Thanks in advance.
