I found it under Discover >>> Horror >>> sort by Popularity AND by Date.
And since you've recently updated, it was much easier to find it by Date.
That being said, i think it's worth mentioning that even though my comic is just about always in the top 10 from the Crime/Mystery genre, there was this one time where i didn't update for over a month, and i just straight up couldn't find my comic anymore.
The moment I made an update, it showed right back up at top 10 (top 5 even)
probably all just part of their algorithm.
I mean even LYFE who held on top spot since forever, with its almost 320k subs, just disappeared from the Crime/Mystery tab because it didn't update since Dec 11 (the author moved on to PH).
Their system seems to simply favor those who often update their comic over those who do so once in a blue moon.
just an observation.
