I found this question: https://moodle.org/mod/forum/discuss.php?d=316579, but there is no solution provided. I found nothing in the Badges FAQ.
According to this article: https://docs.moodle.org/26/en/Managing_badges, "The badge notification instant message appears to be sent from the
primary site admin for site badges and from the primary teacher for
course badges." I only see Teacher as a role and nothing anywhere about or for Primary Teacher. I created the course. I also enrolled myself as a Teacher. No change.
Editing the "Issuer" fields also has no effect on this.
How do I change the From contact for Badge Notifications?
