Apple's online shop and recently launched streaming music service have stumbled, experiencing outages as the company prepares to release its quarterly earnings figures.
Apple Music and the App Store were among online offerings listed as having trouble at a support web page posted by the California company behind iPhone, iPad, iPod, Apple Watch and Macintosh computers.
"Users are experiencing a problem with the services listed above," Apple said on the page on Tuesday, not offering specifics regarding what was causing outages.
"We are investigating and will update the status as more information becomes available."
Apple is set to report quarterly earnings figures after the close of trading in New York City.
