Hello, NitashaN!
Thank you for contacting Microsoft's Community.
Based on your inquiry, we understand you have passed the Exam AZ-204: Developing Solutions for Microsoft Azure; however, your Microsoft Certified: Azure Developer Associate is not visible on your Certification Profile. We will be happy to help you.
If you are still unable to find your certificate, we opened a Private Message where we have requested information related to your Learn account to verify it and properly assist you. You can find the access to the Private Message, on the top right corner of this screen, as shown in the image below.

We are looking forward to your information. Just a heads up, remember to only send your private information through private message, in order to protect your data.
If no response is received within two business days, we will proceed to close and lock this case as well as the Private Message.
Kind regards,
