A recent update to the iOS version of Snapchat led many users to complain about constant crashes. The main culprit seems to be a maintenance update on June 28 that introduced the bug to the iOS version of the app.
A lot of Snapchat users took to twitter to complain and the company assured users that they were looking for a fix. Many of them reported a similar pattern where the app just closed with the error message, "Something went wrong - please try again later".We're aware of an issue with the latest version of Snapchat available in the App Store. Hang tight, we are looking into it and working on a fix!
