How can I keep the currency consistent at checkout?

Hiya guys, I’m having an issue.

When someone is on my store the products show in their currency which is fine how ever at checkout it goes back to USD. Is there an app to change this?

Hi,
Actually multi currency checkout is only supported if you are using Shopify Payments.
for more details, you can visit official document here https://help.shopify.com/en/manual/payments/shopify-payments/multi-currency/setup

Note that Shopify Payments is available only to stores in certain countries and regions.

Hi, I am trying to figure out this problem. How did you solve this please? Because I am really desperate, I am looking for solution with this. I have shopify payments, shopify markets and I have tried multiple third party apps but none of them can change currency in the checkout. And shopify support doesnt help.
