The BBB activity seems to behave differently from any other Moodle activity in that its description:
- can only be found under the "Show more..." link in the activity edits;
- cannot be forced to display after entering the activity (the only possibility is to use the "Display description on course page" option, which consumes the course page space plus is really not the same and can be easily overlooked if the activity is entered from a link in e.g., Moodle 4's course-index side menu)
Many thanks.
