@Shashi_Deshetti: Hi Team, We have deleted the following post from the build, but looks like Render has cached on its CDN and serving it from there: https://health.factly.in/general-vaccine-trends-in-india-4
We tried doing the clear build cache and deploy option but it is still the same. Any help is appreciated.
