Shiny hunt method with herba mystica not working

[tonytera14]

First off all, I wanna apologize if this is not the correct topic for this question, but I have this doubt and I'm a non-English speaker and need some help.

When I started playing Pokémon Scarlet & Violet in Switch, I used to make shiny hunt using the sandwich method, with herba mystica. It used to work well, with lots of spaw and one shiny for hunt. 

But, since the realease of the SV's DLC, the method seens to not work at all! The spaws are the worst, almost none pokémon showing (unless it's a mass outbreak - that naturally already have a huge spaw) and zero shiny (even in mass outbreak). 

I don't understand what it's happening, the method used to work so well and now looks like it never existed (the last time I had a sparkling level 3 in Blueberry academy e no shiny appeared). Anyone have the same problem? Or know how to solve it? Thanks a lot!

I think the shiny hunting method using herba mystica is no longer effective after the release of the Pokémon Scarlet & Violet DLC. Users have shared that they used this method successfully before, but now the number of Pokémon spawning has decreased significantly and no shinys appear, even in mass raids.  geometry dash deadlocked

This is an interesting topic, reflecting the change in game mechanics after the updates, and can provide valuable information for those who are looking for shiny in the game.
