Hi Hugo , thank you for using Leconfe.
First, to proceed to the peer review stage, please make sure that an editor has been assigned to the submission. One common reason why the review stage cannot be started is that the same user who created the submission is also acting as the manager/editor. In this case, the system automatically assigns that user as the author, which prevents them from managing the review process.
If this happens, you will need to assign another user who has an editor role to handle the submission and continue it to the review stage.
After you successfully enter the review stage, you may refer to the following documentation for guidance:
