Hi,
Go to your My Learning page, under your avatar choose your Profile, from the menu that now appears on the left, go to Credentials. On the middle of the page you now see to tabs, Applied Skills and Certifications. THIS is the certifications you need to choose. Under that Certifications tab, choose the "View certification details" under the certificate of your interest, that will open up the certificate graphic. Since there is no download, choose print to PDF to obtain your certificate.
Kindly accept if it helps , Thanks
