Hey @bhuwan1998
I am interested in working on this issue. Can you assign me this issue?

[bhuwan1998]

@bhavik001 I am not a contributor of this project so I cannot assign you this issue. I do not know how to reproduce this issue if someone is not deploying on netlify. The changes are seen in the production preview on netlify but when published/deployed no changes are to be seen on the successful deployment.

@bhuwan1998 if you clear the netlify cache + deploy from the netlify UI does the issue get fixed?

[bhuwan1998]

@ChrisLaRocque thanks for the suggestion. I tried it and it works
