Sync requires an available iCloud account, network access, and the same app container on compatible devices. Initial merging can take time.

Checks to make

  1. Confirm each device is signed in to the intended iCloud account.
  2. Check network connectivity and Apple system status if several iCloud apps fail.
  3. Open diBirthday Settings and confirm Sync with iCloud remains enabled.
  4. Keep the app open briefly on each device.
  5. Compare a newly edited test record after allowing time to sync.

What the result tells you

  • Disabling and reenabling sync repeatedly can complicate diagnosis.
  • Conflicting edits may be resolved during merge based on stored record updates.

Before trying again

  • Record which device made the latest change.
  • Before reinstalling, confirm important data exists on another device or backup.
