Developers including Amazon and Spotify have been able to update their apps to avoid Apple's 15% to 30% commission.

By Mike Scarcella (Reuters) -Apple has failed to persuade a U.S. appeals court to pause key parts of a federal judge's order requiring the iPhone maker to immediately open its lucrative App Store to more competition.

A U.S. court denied Apple a stay on a ruling that requires the company to stop charging developers for payments made outside the App Store through links in apps.
