It might be helpful to find articles on support.workfront.com that talk about permissions and access to the different objects in Workfront. This is a good one for starting to understand task permissions:
https://support.workfront.com/hc/en-us/articles/216606898-Understanding-Task-Permissions Access to objects in Workfront depends on multiple things -- license type, access level settings, project permissions, individual task permissions, etc. Whenever I troubleshoot, I start with the individual item -- do I have sharing permissions to it? If not, then I fix that. If I do, then I look at the other things that might affect my access. Allison Lippert Workfront Training Manager allisonlippert@workfront.com
