Autostart Pluin not work en Volumio 3.512

I am using Volumio 3.512 with a Premium account on a Rasp 3 with Allo Boss DAC. Interface Manifest. I can’t get the Autostar Plugin to work, neither with Play from last position On or Off, nor with 10000, 20000, 30000 ms. In the Playlist I have different options of Radio Paradise.
Is it a known issue?
