Greetings all~ Happy Wednesday~  Looking for "forum users input" please.  I have

Created a certificate
Mapped a Learning plan to it
Added it to the LP
Configured the Learning Plan Completion Certificate message
Completed the LP
Message was received without the attached certificate....

Any guidance in a step I have missed would be appreciated~ Thanks in advance~ :-)
