Well maybe I live in my own universe. And it's really nice here :D. But maybe you try to select at least one time a lib and you see that the message is gone. If you don't like ant of the libs then select Google Stock lib. It's so easy...
I like Flux by giannisgx89 and LINEAR from DeadmanXD for dark and black themes for the main UI look. For other apps (or ones that are incompatible/look better) I use PitchBlack or Swift Black as they are both very frequently updated.
Thank you for all of your time and hard work!!!

Guys what text editor do you use stupid sh*tty Google docs just turns it into PDF... Ideally with no ads as it's a simple text editor...
So far, a little over a day, it seems to be working on stock 9.0.13 with Magisk on v19.1. No major issues, reboots, or such with my usage.
