ignoreDifferences for syncPolicy

[GurayCetin]

We're observing an inconsistent behavior where manually disabled auto-sync in the ArgoCD UI automatically re-enables itself after an unpredictable period. This occurs despite:

Explicitly clicking Disable Auto-Sync (which changes the button to Enable Auto-Sync)

Attempting to use ignoreDifferences to prevent syncPolicy modifications, but it's not effective to ignore it.

Application config;

  syncPolicy:
    automated:
      allowEmpty: true
      prune: true
      selfHeal: true

ignoreDifference on application

  ignoreDifferences:
  - group: argoproj.io
    jsonPointers:
    - /spec/syncPolicy
    kind: Application
