Location wise currency of products is not showing.

I have purchased this plugin(CURCY – WooCommerce Multi Currency – Currency Switcher), I wanted to show the currency of the product location wise like if it is in India then show it in the INR and if in US then show in dollars.

I have made all the settings after seeing the document but when I check location wise, it is not working properly.

It changes when you change it from currency bar but does not change location wise.
