Brazilian antitrust regulator Cade said on Monday that Apple must lift restrictions on payment methods for in-app purchases, among other things, as the watchdog moved to proceed with an investigation into a complaint filed by Latin America e-commerce giant MercadoLibre.

According to Reuters, the complaint filed by MercadoLibre in 2022 pointed out that Apple imposes its in-house payment system upon developers that offer digital goods or services, and prevents these developers to redirect buyers to their own websites and do their transactions outside the app.

Apple’s App Store anti-steering rules have been declared illegal in Brazil, in the latest antitrust ruling against the company.

Apple has only 20 days to open up in-app purchases, or it could face $43k in fines per day if it fails to comply with the Brazil antitrust regulator's ruling.
