As soon as a license is assigned to a participant, it is considered assigned.
However, if the license is no longer required, it can be withdrawn by deleting either the participant or the corresponding course.
If the course has not been started by this time and the license has been assigned for less than 30 days, the license is automatically credited back to the license account and is therefore available for renewed use.
Otherwise, i.e. if the course has already been started or the license has been assigned for more than 30 days, the license is considered used up and cannot be credited back to the license account.
