Hi There.

I am a total newbie in Netlify.
I somehow managed to deploy my react app to Netlify.
It’s URL :
Everything works fine except that, whenever I reload the page with some route other than the home URL, i.e.,

For example, whenever I try to reload the page with address ,

I have to go back to the root URL ( to make it load properly.

Can anyone help me through this?
