Hi Cornelius,
It was actually rather strange because you are correct, there was no option to attach any documents in that category. However, after I received the email from PMI the next day asking for more information, I was able to go back to my submission in my PMI Dashboard and edit my submission. At that time there was a field to attach documents, so I ended up attaching my PDF certificate that I received at the end of the course. Once the submission status changed to "In Review," I was no longer able to edit the submission. They mentioned it would take up to 10 business days to complete de the review from the time I submitted the certificate, and they only give you 3 days from your original submission to submit the supporting documents. I apologized and asked for an exception because I ended up replying directly to the email from PMI with the attachment, and after 5 days of not hearing back I realized the email from PMI is a DoNotReply email, so I read the steps carefully and realized they wanted me to submit the document directly in the dashboard. I'd be curious to hear what others are experiencing. Thank you for your response!
Regards,
