When this started to happen I tried to see anything in the log inside MM, but since I had to restart to get Magisk to work (and to access the log in MM) it was cleared and only showed since reboot.
Can't access /cache when the root+Magisk ain't working, and after reboot the Magisk log seems to be cleared. The backed up one is only showing init messages and hide_list and proc_monitor messages.
Is there some way to get access to /cache w/o reboot or is it automatically backed up at reboot? If so, there doesn't seem to be any errors.
The Magisk log is cleared on a reboot, but the previous log is saved as magisk.log.bak.
