The European Commission has opened two formal antitrust investigations into Apple’s App Store and its Apple Pay payment system.

The investigation into the App Store comes after a complaint from Spotify in March 2019 and a subsequent complaint from e-reader company Kobo, over how Apple takes a 30 percent commission on every subscription signed up through its App Store in the first year, and then a 15 percent cut.
