I'm currently experimenting with Workflow. I've got 2 user (editor) accounts, one is in the approval group, and one isn't. However, my user who is in the approval group, can't publish directly. They still need to request publish. Can I change this somehow ? Changes he does are automatically published after he initiates the workflow though, but rather have him directly able to publish.

Make sure to open a support case for this, probably not enough people here who will know the answer (me included 😅 )

Any user with access to the workflow section is treated as a workflow admin, and will be able to publish at any time. Other option is the extends permissions setting, which will add workflow buttons rather than replacing the CMS defaults for each user, so users with save+publish will see that button as well as the workflow options

Thanks! Ill add him to the workflow section 🙂
