As the corresponding or submitting author, you can track the progress of your article online via Your research (login required). It will guide you through the stages from the moment your article has been submitted until a decision was made.
Every step is described and will let you know whether any action is required, which you can then perform as appropriate by clicking on the respective manuscript, leading you to the submission system.
You can also access it via the starting page of your Springer Nature Profile where you will need to login and navigate to "Your research". Scrolling down, you will find the section called "Your research", which is separated into two tabs "Submitted" and "Published":
Depending on your selection, you will either see the statuses of your submitted manuscripts or already published articles. If your manuscript has been accepted but does not yet appear in the "Published" section, it may still be in the Next steps for publishing your article or in production. Once published, please allow around two weeks for your article to appear under the "Published" tab.
If you are facing any difficulties, please consult My submission / publication is not showing on my Springer Nature profile.
