Accepting Multiple Currency Payments with Third Party Payment Gateways

[MoonBaseDisco]

Hi, I set up my store in my home country Turkey without any problems. My Currency for this market is the Turkish Lira.

I use iyzico as a payment gateway. I also have an extra subscription that allows me to collect in USD and Euro along with Turkish Lira.

But when I set up a European market to sell abroad I ended up with a problem.

When I select "Show prices to customers in their local currency." option to show European customers the price in Euros,  an error prompt is shown which says : "The shop's payment gateway does not support enabling more than one currency."

Shopify Payments is not an option in Turkey. But my payment gateway already allows me to collect in 3 different currencies. 

What am I missing here? 

Thanks!
