Facebook apologized after its latest software update caused rival apps to crash on iPhone and iPad.
Popular apps such as the Tinder dating service, the Spotify music streaming app and the TikTok video platform were among those rendered unusable.
The issue was with apps that integrated the “sign in with Facebook” feature, eliminating the need for a separate username and password.
Facebook said it “quickly identified the problem and solved it”.
Wednesday updated the software development kit (SDK) used by app developers to integrate its services.
But independent developers soon warned, on the Github coding site, that it was blocking their apps.
And Thursday, Facebook said, “Yesterday, a new version … included a change that caused some users to crash in some apps using the Facebook iOS SDK.
“We apologize for any inconvenience.”
