Limitations for Nested Reference Publishing

Nested Reference Publishing feature is plan-based. Please contact the support team to get this activated for your organization.
Entries can now be published with nested references up to a default depth of 5 levels, for both single and bulk publishing, and can vary as per your organization’s plan.
You can select up to 50 environments and locales to which you want to publish content.
When bulk publishing entries, you can only select a maximum of 100 parent entries.
While bulk publishing entries, you cannot view the nested references of all parent entries within the tree.
It is not possible to select specific child entries of a parent entry while publishing.
If any or all of the nested referred entries are already published in a specific environment and locale, they will be skipped when publishing the parent entry.
If any of the nested referred entries have an error, the other nested entries at lower levels of depth will not be sent for publishing.
During multiple bulk publish tasks in an organization, only a maximum of two jobs will be active at any given time across the entire organization.
You cannot cancel individual items once a publish job is scheduled. You can only cancel the whole publish job.
The nested reference feature is not supported when publishing entries via releases.
