Sorry for commenting a year after posting but I have a question...
It seems that Medium since Q3 or Q4 2019 has been making all non-Medium domain links nofollow. This is understandable BUT it also means that those of us with custom domains have all their internal links labled as nofollow too.
For some reason, a few publications out there with custom domains likes the Writing Collective and Towards Data Science have do follow links for their domain only. See the below links for examples...

I'm trying to figure out why this is the case but can't for the life of me. Moreover, Medium's support is hush on the matter too.
I guess I could use the Medium domain version of the URL to get a dofollow link but then it's like I'm linking off site to a page that gets redirected onsite.
Any idea what to do as the change to nofollow tanked my SEO in 2020?
