Autostart on V4 does not appear to be working. I have autostart plugin ver 4.0.4.
This is using my v4 test system comprised of an rpi3 and a touchscreen and a hifiberry dac.
For me, autostart is critcal and I would not move to v4 without this functionality.
Let me know what debug info you would like as it is setup permanetly on my V4 test system. thank-you
