These releases invoke the checkAccessForAssetSubscription method, which is only available in Now Assist Admin Console version 6.6.4 and later.A known issue with the Now Assist AI Agents store app introduced an access control list (ACL) check in version 5.3.0 that calls the checkAccessForAssetSubscription() method. This method requires Now Assist Admin Console version 6.6.4 or later. Because the version dependency between the two store apps was not strictly enforced, some instances updated Now Assist AI Agents to version 5.3.0 while Now Assist Admin Console remained below version 6.6.4.There is an issue with the Now Assist subscription or entitlement contract on the instance.When upgrading from Xanadu to Yokohama or Zurich, a daily scheduled job called Licensing Engine runs after the upgrade completes and populates the subscription_has_family table with a record where Application family is set to Now Assist for Fulfiller, based on the instance's Now Assist entitlement. The symptoms described in this article may appear until this scheduled job completes successfully.
