Spotify, Venmo, and other iOS apps went down because of a Facebook SDK

The new Facebook software development kit wreaked havoc on a number of iOS apps for over an hour on Wednesday — causing them to crash for hundreds of thousands of users.

According to users on Twitter and GitHub, the new software development kit, or SDK, caused a range of apps to crash  — including major apps like Venmo, Waze, Spotify, and more. The SDK essentially allows those apps to connect to Facebook and use some of its features, like allowing users to log in using their Facebook account. Thankfully, the issue seems to have now been fixed.

DownDetector reported huge upticks in crashes on many major apps, including Spotify, TikTok, Tinder, Viber, and more. Based on tweets, it seems as though the Spotify app had been down for almost two hours starting at 3 p.m. PT.

The issue itself simply caused apps to crash right after opening — essentially rendering them useless. While there were unofficial workarounds, like blocking the “” domain in a router’s DNS settings, those fixes were complicated and wouldn’t work when not connected to Wi-Fi.

The Facebook SDK essentially allows users to be able to sign on to an app through Facebook — but even people who don’t use Facebook to sign in to apps and services may still have been affected. That’s because the apps still have that feature as an option, and as such still include the Facebook SDK code.

Facebook has yet to respond with a comment, but we’ve reached out to the company, along with the developers of many of the major affected apps, and will update this story when we hear more.

List of apps that were affected by the Facebook SDK

A number of major apps seem to have been affected by the issue, including some of the most popular apps out there. Here’s a list of some of the apps that we could confirm weren’t working, though it’s likely that many more were affected too.

  • Spotify
  • Venmo
  • TikTok
  • Pinterest
  • Waze
  • Calm
  • Postmates
  • Viber

Apple’s iOS 16.4 beta brings new emoji, web app notifications, and more
Sample of new emoji coming in iOS 16.4

Apple has just released the iOS 16.4 beta for developers and anyone else who wants a really early look at the new software. This is the first beta for iOS 16.4, following numerous releases for iOS 16.3.

The first highlighted items for iOS 16.4 are the new Unicode 15 emoji. These are the first new emoji in over a year. Some of these new emoji include a shaking face, pink heart, light blue heart, goose, donkey, angel wing, jellyfish, pea pod, ginger, folding hand fan, maracas, flute, and more. These new emoji additions were originally proposed in July 2022, and they were added to the Unicode standard in September 2022. It has taken a few months for these to get added to iOS because designers at Apple needed to create the icons with the information provided by the Unicode Consortium.

Using an Android phone showed me just how bad iOS notifications really are
iPhone 14 Pro with iOS 16 notifications compared to Google Pixel 7 with Android 13 notifications

I’ve been using an iPhone for over a decade. I received the original iPhone as a birthday present in 2008, and after just four months of use (without a case, of course), I dropped and cracked the screen. With the iPhone 3G about to launch, I decided to upgrade to that, and I’ve pretty much bought a new iPhone every year since — including the iPhone 14 Pro.

Before Apple added Notification Center in iOS 5, notifications were just alerts that would interrupt whatever it is you were doing, until you took action on it or dismissed it. And once you dismissed it, that was it — it vanished, never to be seen again, so you may have missed something important if you didn’t remember what it was.

In 2007, Steve Jobs introduced the iPhone on the stage at Macworld Expo in San Francisco. It has been 16 years since that announcement that changed the mobile industry as we know it; today, we now have 16 versions of iOS software that power our iPhones.

iOS has certainly come a long way, with iOS 16 letting us do things on our iPhone 14 that we never thought was possible a decade ago. But each version of iOS has its own strengths and weaknesses, with some releases being better than others.
