Thanks for your reply. I'm not from the US either. I have a PayPal account and I've linked my payment method to it. However, when I try to make a payment, PayPal prompts me that I haven't linked a payment method. I noticed that if the merchants on itch.io offer credit card payment options, this issue doesn't occur. It's frustrating because it limits me to using PayPal only with merchants who offer credit card payments, which seems odd.This problem seems very common in China. I'm sorry
