Facebook admits that it was to blame that apps on iPhone and iPads stopped working on the 10th of July.
Some apps like TikTok, Tinder, Spotify and Waze were unusable for serval hours during the day.
Many users took their concerns to social media in a range of angry and aggressive content.
Facebook said in a statement: “Earlier today, a code change triggered crashes for some iOS apps using the Facebook SDK [software developer kit]. We identified the issue quickly and resolved it. We apologise for any inconvenience.”
The reason Facebook has the ability to affect these separate apps, which may not be part of the Facebook group is because they are integrated with Facebook.
A similar incident happened in May and after that first crash, app developer Guilherme Rambo wrote: “It was as if Facebook had an ‘app kill switch’ that they activated and it brought down many of people’s favourite iOS apps.
“Of course it was a bug and not something done intentionally, but it highlights the point that they do have control over apps that include their code.”
Android users have reported no such issues.
