I think the Admi can do it

Hi @mbabaei,

If this user has both author and journal editor and had submitted the manuscript as an editor, they will be able to edit the metadata after submission and review.

Otherwise, only a journal editor or journal manager can edit the metadata after submission.

Kind Regards,

User could edit metadata
