itch.io

i can buy other assets from itch.io, paypel doesn't let me  to pay for starbird using debit card, but can pay for itcho.io.  

paypal told me my account is normal, i don't know the reason. i use debit card, no credit card.

thanks, i send message to paypal, maybe it's their issue. btw, i can pay for itch.io

i can't buy this ,  payment method is paypal,   unionpay can you solve it ?
