Describe the issue or problem
We published an issue, which has a doi assigned, but if I try assigning doi to articles in that issue (having first unpublished them) I can click assign and be shown a doi, but the “Save” button is greyed out.
What application are you using?
Problem solved: You must assign yorself in Workflow Copyeditor Privileges as well the following Permissions:
“Allow this person to make changes to the publication, such as the title, abstract, metadata and other publication details. You may wish to revoke this privilege if the submission has received a final check and is ready for publication.”
