Spotify, Pinterest and Tinder are blocked on iPhones 0:53
(CNN) - Popular apps like Spotify, Pinterest and Tinder crashed on iPhones on Friday in what appeared to be a widespread outage linked to a Facebook bug.
Reports of malfunctions soared at DownDetector, a service monitoring site, around 7:30 a.m. on Friday (Miami time), and users and developers voiced their frustrations on social media.
At 10:30 a.m., Facebook said in its developer forum that a bug in its iOS Software Development Kit (SDK) had been resolved, about eight hours after it started investigating the increased failures.
Many app developers use this SDK to allow people to use their Facebook login information to log in to other apps, although users did not have to be using Facebook login to be affected.
It was a frustrating Friday for developers and users of these apps, especially since a similar outage linked to the Facebook SDK occurred in May, according to tech news site The Verge .
