\affil: ! Undefined control sequence.

[jd-s]

When trying to compile the new template (lni-author-template.tex) with pdflatex, I receive the following error:

! Undefined control sequence.
l.26 \affil
           [1]{Universität\\Abteilung\\Straße\\Postleitzahl Ort\\Land}
? 

Any idea how to solve this? Of course, this error persists when working on the paper...

Thank you!

Which version of lni.cls do you use? \affil is a new macro defined in v1.8

I was facing this issue as well. It turned out that Latex used an outdated version of the LNI style from TexLive instead of the current version which I had downloaded manually. v1.8 works well for me.

@jd-s Download https://github.com/gi-ev/LNI/blob/main/lni.cls and store it next to your .tex file.
