Limiting the scope of the currency Converter

Hi,

The base currency of my store is USD. I just want to display the Converter on the checkout so that the user can checkout with his currency choosing.

I used wp logic: is_page( ‘checkout’ ) and at present, the slider is limited to the checkout page.

Now the issue is after I select a different currency and checkout. From that point, the currency is Changed and is applied to the whole site. I know that is the expected behavior but my requirement is slightly different.

It is also breaking display of pricing where I have pulled products using woocommerce shortcodes.

Upsells Section:

So, How do I reset the currency to Default once the “Thank You” page is reached? If that is not possible, How do I only restrict the Converter to the Checkout Page only?

At present Cache is Disabled.
