I am submitting an article to Scientific Reports. I used overleaf to write the manuscript, with the SR template. Everything worked great. However, when I upload the main.tex file and the biblio.bib files to the platform, the bibliography does not show.
I am aware they are changing their submission system, but I must re-submit in the old one.
I do not have access to the compilation errors, since it is a submission platform that builds the pdf.
I was hoping someone had similar trouble and knows how to solve this problem.
