Hi, @akhalid010. The DNS records in questions are working when I test but they may not be working for you due to DNS record caching behavior. The delays in DNS record changes are caused by the design of DNS itself. There is a support guide with more information here:
There is nothing that Netlify can do to speed up this process at the caching it happening outside of Netlify’s systems.
If there are other questions about this, please feel free to reply here anytime.
