Paypal will charge you a fee if the currency is another currency. Also yes it does have a limit on Brazil: https://developer.paypal.com/docs/classic/api/adaptive-payments/Currency-Restict...
I bet that it also makes it impossible to use that old integration (sell and instantly x% go to dev and y% go to itch), right?
you will still have the same experience and problems with BRL currency, there is no changing it. Brazil made it very hard to get anything free on tax.
I must agree with you. -_-
