Hello,
Why does this problem occur? How can I fix it? (Shopify Payments)

Sounds like you're using a bank account that isn't in the same currency that your Shopify store is set to.

Yes, but later I set Shopify store currency like using my bank account. Doesn't work

But another problem is I want to sell a product for example to the USA, They use the USA Dollar and I must set my store currency Dollar.  But my country and my bank account give us our currency. How can I fix it?
