Apply remains blocked until Failures = 0, Warnings = 0, Unmapped = 0, Missing = 0, all explicit clears are reviewed, image import is disabled or V380 accepts the logo asset, one representative WordPress edit screen is compared with the export and proposed row, and a post-Apply zero-change Preview is completed.

  • Official support, sales, and security channels
Considerations

Cons

Teams must validate permissions, retention, regional processing, false positives, and remediation authority.
