Lightroom on iPad 11, M1

Happy new year, editors. 
I have been struggling with editing photos on iPad 11 m1. 
I believe this is a strong chip that should be covering this feature, but instead lightroom is very slow, closing completely after almost every edited picture, not saving editing progress and crushing, and brushes are super slow to work with, same as rendering. 

What are your settings? Is it a way to make it work faster?
