What happens if I forget to add taxonomy topics when I submit my paper? I submitted a paper recently to an elsevier journal. During the submission, I forgot to add the taxonomy topics related to my manuscript. After I completed the submission, I received an email that the manuscript was received successfully. However, it has been 2 days and the manuscript status is still "With Journal". Is this because I forgot to add the taxonomy topics. If yes, what should I do to fix this. 

Thanks in advance for your help ...
If this is an issue, it will most likely be flagged by the production staff when the paper is returned from review. But it typically takes a few days to get sorted through the editorial system, so it shouldn't be the lack of taxonomy holding it up.
