I have to use Springer `[sn-mathphys]{sn-jnl}` template to submit a paper and I'm afraid that I'm unable to generate the bibliography. Not even when I use the sample file `sn-article.tex` that they provide, without changing anything! However, when I compile the file changing the style to
`\documentclass{article}` everything goes fine.

I've tried TexnicCenter and with Winedt; both of them with Biblatex and Biber. In all cases, I keep on getting the error:

```
" Cannot find 'sn-article.bcf'!"

```

The format can be found here: <https://www.springernature.com/gp/authors/campaigns/latex-author-support>

I've searched the web for hours and I've tried many things. Neither one worked. For example:

1. add at the preamble `\usepackage{natbib}`
2. Create the .bbl file and then use `\input{sn-article.bbl}`

I've seen that many people have had this same problem for years, but I'm afraid that the solutions that they applied are not working for me. Can anyone help me, please?
