[Magisk] madm03:
Hi, i now that everyone seems to be able to use magisk under oreo, but i can't get it to work since the first oxygenos oreo beta release. Never had a problem with previous versions.

the funny thing is, it seems to install correctly, but after the reboot there is no magisk manager, and no root functionality.

What i tried:

* Dirty and Clean flashed every beta and stable build.

* Tried the last 4 magisk releases, last version 15.3

* Supersu, which works every time

* TWRP 3.2.1 blu spark 8.61

I deleted everything except /data/media/0/*

Also, a log file from a magisk install after a clean flash:
