Help.

go to any manga, scroll down until u see a bunch of grey tags for the manga, click any of the tags and there u have it. the search bar for the tag will pop up afterwards also

What I do (on mobile too) is click a comic, then click a random tag, then on the far right there is a “search tag” and I just type the tag I want to search.

go to a manga's screen and click any tag then you will see a button for searching other tags

here's a random tag btw if u're having trouble:
