Automatic Rediscovery Does Not Run After Updating Vendor Group Priority

DX NetOps Performance Management
did not run rediscovery after I updated the vendor certification priorities and updated the order of vendor certifications.
Updating the order of vendor certifications and the PriorityGroup tag in the same REST operation can disrupt automatic rediscovery. Manually trigger rediscovery for the affected metric family.
Follow these steps:
  1. Mouseover

  3. Select the affected metric family.

    Update Metric Family
    Discovery runs for all devices in the metric family.
