Known Issues

As of now, you can only invite users who have a Box account (any plan) to collaborate on a Hub.

​
User and enterprise migrations

Migrations have a negative impact on all Hubs created in the enterprise:
  • When a user migrates their content, the files and/or folders in a Hub become unavailable.
  • Enterprise migrations make all Hubs unavailable.

​
Limitations

  • Shield’s Information Barriers are not supported in Hubs.
  • Version history is not available.
  • As of now, Box Hubs does not work on mobile.
  • There is no current file or folder limit for a Hub. However, Box Hubs is meant to have curated content, not to serve as a location for root folders.
  • Hubs does not support an editable shared link to a Hub.
  • Instant Login (admin only feature) doesn’t work with externally collaborated hubs. An admin can’t use instant login for a user in their enterprise and view content owned in another enterprise’s hub.
  • As of now, you can only add external collaborators using their main email address. Using an email alias results in an error We were unable to add [xyz] as a collaborator.
  • Hub collaborations are not shown in the External Users tab in the Users & Groups section of Admin Console.
  • Box Hubs is not fully interoperable with all features within Box, such as Box Shield and Box Governance. This limitation may affect your ability to meet compliance requirements that depend on these services.
  • As of now, images and text included as a block within a Hub have different data handling measures than files and folders.
