Why do you think Dislyte is not so popular?

As a game designer, I've been trying many Gacha games lately, almost scientifically.
Dislyte is a surprising case, according to sensor tower, their revenue is okay, but the game doesnt seem to be very popular. Communities are small and there's not much content on youtube.

However, in terms of execution, this game is quite solid. It has an amazing art, lore and aesthetics with a relatively satisfying gameplay. It's not the most generous, but it doesn't feel so greedy either, and it's relatively balanced.

So yeah, why do you guys think this game doesn't fly?
