Hello i decided to give it another try when i saw this os is based on lineage so this build must be based on K9100ii builds
so i got everything to work including bliss launcher
the problem is the onscreen nav buttons natively enabled which i think bliss launcher does not support
the solution is once you boot the rom for the first time and bliss launcher does not respond do not close it and hit app info instead , then complete the rom setup
then go to settings - system -buttons -enable on-screen nav bar
then go back and to to buttons again and disable taskbar and on-screen nav bar
then everything will work bliss launcher will be normal and app switch button will work
