Wero does have recurring payments planned too (apparently for end of 2026), seems like they're well aware of PIX and racing hard to get into exactly the same space.
Direct Debit is very nice, largely because your bank manages the subscription; companies have to declare the payment ahead of time and if you get balance mixed up for some reason, then the bank will just do the payment whenever your balance is correct if it happens within a week. I've had credit cards decline on subscriptions before because I didn't have enough loaded up on them. Never had that issue with SEPA.
Either that or "credit cards just work", so very few entities bothered until now.
