The promise of a Taylor Swift concert film may have lured plenty of fans to Apple Music. But when they got there Sunday, many were frustrated by crashes, glitches, buffering and a user interface that many of them found confusing.

The Jonas Akerlund-directed video, “The 1989 World Tour Live,” which takes footage from a concert Swift played in Sydney, drove a huge amount of interest when Swift and Apple Inc. announced it Dec. 13 on social media, and many speculated it could give Apple a huge leg up in adding new trial subscribers during the holiday season when it launched Sunday.

Instead, it got a rush of fans that overwhelmed the service. The video frequently crashed, or skipped, or refused to load at all. More than a few people found themselves confused by Apple Music’s layout, trying to get the video to load from Connect, an area of the service meant to be filled with social media-style updates from specific artists, rather than a place to consume video content. That confirmed criticism that Apple Music's user interface might be confusing to users, a charge that came up frequently in critics’ assessments of the service when it launched.

While there were some reports that Apple had gotten a grip on the situation by Monday, complaints persisted through Monday morning.

On Monday, Apple Music representatives were still working to help distressed fans who encountered issues with Swift's concert video.

Neither Swift nor Apple Music has commented on the issues.
