@manton I tried twice, but I will try once more:
I noticed that footnotes are broken on my blog page: e.g. this reference here https://blog.martin-haehnel.de/#fn:1
is used in at least two different blog articles at the moment.
I did some research and this forum post seems to suggest that there is no solution for goldmark based hugo: https://discourse.gohugo.io/t/does-goldmark-support-namedfootnotes/26727
However I would imagine that pandoc can handle this. Can I somehow use pandoc to render markdown with micro.blog?
