On Android 5.1.1 everything worked fine with Automagic 1.28. After upgrading to M I noticed "keyguard off" was doing nothing

Thinking it may have to do with M I tried newest EAP 1.29 but still no luck. Keyguard off does not work for me.
Flow completes without error but phone is still locked with pattern

Some more infos: Automagic is granted device administrator, notification access, service is running fine, root tools installed, supersu granted.
I'm rooted with Chainfires boot image and supersu 2.52 beta (selinux enforcing). May there be general problems with new selinux handlers / security policies in M?
Am I missing something?
Can anyone test "keyguard off" on Android M and confirm this?
Help would be highly appreciated

Thanks
