Sorry for late response, because of I am delivery an ISMS audit in China last week.
Actually, ALL certificate have been issued 2 months ago, in our online course system. Do you remember all student they have a course ID and password used in the class? They can use the same ID/Password to login and see the their own certificate immediately…
Please ask our client (students) to check their name is correct, if not, they can simply goes to the “edit profile” to change/update their name.
Please let me know is there any problems.
