Can you no longer change currency in which PayPal charges your credit card?

I have 3 credit cards - loca, local in USD and Payoneer in USD. I have tried to buy something on eBay through PayPal when transaction was in Russian Rubles. Since I chose Payoneer debit card PayPal wanted to charge it in GBP for some reason while it is in GBP. That was no good as I don't want to pay conversion fees so I tried credit card with USD currency and guess what, PayPal wanted to charge it in local currency. I thought it has to do with original transaction's currency so I tried to buy from seller who offers product in USD. Guess what? Same thing:



How is it possible to designate to PayPal in which currency I want to be charged? It seems their system charges in currency based in which country it was issued so it's not good for international transactions. I also want to state that their transition to interface is a mess as it seems they tailored it to teens. It lacks functionality it had before and it just created another learning curve to adapt to new system.

I don't understand these companies. Why the heck do they constantly try to fix something that isn't broken? To stay pretty? Better funnel the capital to more important things.
