Today working on my favorite website - optionsbrew.com, for a moment I faced a small issue - how to display block (s) on the default taxonomy/term page.

I remember I was doing such tricks back in 2012 or 2013 and was wondering does it still applies in 2021, turns out -  it does!

Here is the solution: on the Configure block page, under the Pages tab, enter /taxonomy/term/* and save

Configuring Drupal 8 block

Here is how our taxonomy term page looked before:

And here is after

Hope it helps!
