The Facebook SDK is crashing a bunch of iOS apps today, including popular ones such as Spotify and Pinterest. Luckily you can do something about it, by enabling a VPN or a firewall app that blocks the sneaky code that tries to talk to Facebook. The Verge swears by Lockdown Apps, a free firewall for iOS, so if you’re having issues, give it a go. The VPN costs money, but there’s a trial. It’s likely Zenmate – which I like – will get the job done too, although I haven’t tried any of these for this particular problem as I’ve yet to experience it.
