Facebook Messenger appears to be crashing almost instantly for some iPhone owners. A mobile developer suspects the culprit may be an obscure “CryptoTokenKit” found in the latest version of the software.
Facebook’s massive messaging platform has over 1.2 billion users. But potentially hundreds of millions of iPhone owners who are upgrading to Apple’s latest operating system, iOS 11, may not be able to use the app until Facebook updates it.
I stumbled across the problem personally by updating Messenger on September 18, and then upgrading to iOS 11 yesterday, the 21st. Messenger now opens for about two seconds and immediately quits, repeatedly and reliably, even after a full phone restart.
Want weekly updates? Of course you do …
