A bunch of popular apps are experiencing technical issues on iOS — and Facebook appears to be to blame.

Spotify, TikTok, Tinder, and a bunch of other high-profile services are currently down for some users. Developers on comment threads on Github are blaming an update to Facebook's SDK, or software development kit, for the issue.

The outage-measuring website Down Detector is reporting outages for numerous popular internet services — also including Pinterest, Waze, Venmo, Bumble, SoundCloud, Nextdoor, The New York Times, Walmart, Viber, Pandora, and UPS, according to Down Detector's tracking.

A Facebook worker who is a contributor to Facebook's code repository on Github said that the issue has since been fixed, but may take "a few minutes" to go into effect.

A Facebook spokesperson did not immediately respond to a request for comment.
