Cloud User Account Change Handling

Goal

React when the cloud user account status changes (signed in/out, restricted, etc.).

Actions Required

Action	Purpose
CloudServicesOnUserChange	Listen for cloud user status changes (persistent)
CloudServicesSynchronize	Sync after user becomes available (optional)

Variables Needed

• (optional) lastKnownState (String/Enum in your FSM)

Implementation Steps

1. State: RegisterUserListener (Persistent)

Action: CloudServicesOnUserChange

• Events:

  • availableEvent → CloudAvailable

  • noAccountEvent → CloudUnavailable

  • restrictedEvent → CloudUnavailable

  • couldNotDetermineEvent → CloudUnavailable

2. State: CloudAvailable

Enable cloud save UI and optionally call CloudServicesSynchronize to refresh snapshot/values.

3. State: CloudUnavailable

Disable cloud save UI and fall back to local-only storage.

Notes

• On iOS this commonly maps to iCloud account availability.

• Keep this listener active if your app needs to respond during runtime.
