Spotify has stopped working properly, according to users.
A strange bug appears to make the iPhone version of the app crash as soon as it is opened.
Spotify does not appear to have pushed out a new update to the app.
Instead, the issue appears to be a consequence of problems with Facebook's developers tools. The same issue has led to problems at a wide variety of apps.
There appears to be no simple fix for the issue. Deleting and re-installing the app, for instance, does not solve the problem.
The music streaming service appeared to work on other platforms, including the Android version of the app, according to users.
The tracking website Down Detector saw a huge surge in the number of people reporting problems with the app, in what appeared to be a widespread outage.
Problems were particularly focused in western Europe, according to the same site, though that may simply be a consequence of where the most people were trying to use it.
The Spotify Status account, which it uses to announce outages and problems with the service, tweeted its standard notification that something had gone wrong with the app.
"Something’s out of tune," it read. "We’re currently investigating, and we’ll keep you posted here!"
The outage came on the same day as the release of Juice Wrld's new posthumous album. When it was released, at midnight, users reported that the overwhelming interest appeared to have broken the app, though it is not clear whether the new, more widespread problem is related to that.
