Issue with Manuscript Submission – PDF Format Required by Editors

[qw192837]

This is the first time I have encountered such a situation. My article successfully passed the peer review process, but the editorial office requires me to resubmit it in PDF format. The message I received states:  

"Please resubmit your manuscript as a PDF file. You have resubmitted it as an Adobe file. This is your last chance to submit it in the correct format, or your manuscript will be rejected."

After receiving this request, my manuscript status changed in the submission system, requiring me to make modifications before resubmitting. However, I am facing a technical issue preventing me from directly uploading my revised manuscript as a PDF.  

I have documented my submission process in this **video**: [link removed]

Key Observations from the Video:

1. At the beginning, you can see that the system states in **red text** that while submissions must be in LaTeX or Word format (I formatted my article in LaTeX), **PDF uploads are not allowed as the main manuscript file**.  
2. Before receiving the editor's message, I uploaded my article as a **PDF under "Supplementary Material."**  
3. The manuscript submission system appears to **combine all uploaded files** into a single document, which includes my article. At the end of the process, I confirm this generated document before it is submitted to the editorial team.  
4. On the **last page** of this compiled PDF, there is a **link** to download my article as a standalone PDF.  
5. However, based on the editor’s response, **this approach is not acceptable**, as they claim the file is an "Adobe file" (though I am unsure what this means in this context).  

Since the system does not provide a direct option to upload a **PDF as the main manuscript**, I am unsure how to proceed. The available file type options include:

My Questions:  

• Should I select a different file type from the list above to properly upload my revised manuscript?  
• Is there a specific workaround to submit a PDF directly through the system?  
• Has anyone else encountered this issue when submitting a LaTeX-compiled article?  

I sincerely appreciate any advice or insights from those who have experience with Elsevier’s Editorial Manager system. Thank you for your time and assistance!
