Background App Refresh in iOS 7 reportedly causing login issues for some apps
An apparent bug in iOS 7's Background App Refresh implementation is causing users of certain third-party apps to be kicked out of login sessions, forcing them to reenter their credentials every few hours.
It is unknown at this time what exactly is causing the seemingly random logouts, though The Verge reports that app makers have narrowed down the culprit to a mechanism in Background App Refresh.
Of the more popular apps affected, Mailbox was "in crisis mode" to find a solution, but was unable to rectify the situation, saying Apple's Background App Refresh is the root cause of the issue. Consequently, an updated version of the app disabling access to the feature was submitted to the App Store on Friday.
