The Bitcoin World iOS app has resumed full functionality following a six-hour outage caused by a recent update. The disruption, which began shortly after the update's deployment, was linked to a conflict with Apple's iOS security protocols, leading to authentication failures. The development team swiftly addressed the issue by rolling back the update and deploying a server-side patch. While the core service is restored, some users may still face difficulties locating the app in the iOS App Store due to search visibility issues. The Bitcoin World team is collaborating with Apple to resolve this secondary problem. Users can access the app via direct links or the developer's page in the meantime.
