Today I updated to Magisk-v13.1, first it all worked grade and SafetyNet successfully past again in an App.
Then I tried it in another app, there it didn't worked, so I wanted to restarted the system and looked again if it worked, but then I had lost Root after reboot.
I reinstalled Magisk-v13.1 and tried it again and again, but it seems like it all is working grade, even Magisk Hide on apps like Root Checker and other, but on a certain app (Seqr) it isn't working and after reboot Magisk isn't working at all and Root is gone.
