We are seeing a reproducible behavior change with ManagedSettingsStore.application.blockedApplications on iOS 27.0 (24A437), iPhone 17 Pro, under .individual Family Controls authorization. On iOS 26, hiding an app and later removing the block restored it to its original Dock, Home Screen, or folder position. On iOS 27, the app may reappear elsewhere on the Home Screen, outside its original folder, or only in App Library, requiring manual "Add to Home Screen." We tested setting blockedApplications to nil and [], clearAllSettings(), and deactivating a named store; none reliably preserved placement.
Notably, the same symptom reproduces with no third-party API involved at all using iOS's own built-in "Hide" feature (long-press an app -> Require Face ID -> Hide, then later un-hide it) also fails to restore the app to its original Dock, Home Screen, or folder position. This suggests a more general placement-restoration regression in iOS 27, not something specific to ManagedSettings.
Has anyone else reproduced either of these? Is this an expected iOS 27 behavior change, or a SpringBoard regression? Filed as FB25044883.
