I had passed Developer Associate certificate on 10 Jul 2020 (Apache Cassandra™ 3.x Developer Associate.pdf). As I understand all the details have been migrated to new platform and the old certificate are not compatible. Also upon going through answers for similar questions I found certificates have QR code and can be validated using (https://certification.mettl.com/datastax/applicant/verify-certification-with-qr) , however the certificate which I received doesn't have QR code.
Could you please share an URL or certificate which has this QR code so that I can share it on my linkedin profile to be able to validate my certificate. Thank you !
