Hello,
I've just tried the new firmware 2.20.08 from 12/20/2018, it solves most of the issues i faced with my mag 322 but i noticed that like the other previous firmwares, the deep mode is not functioning with external portals. I activated it in the advanced settings and when i power off the mag with the red button on the remote i have a black screen but if i press a second time the red button a few seconds later, i directly return to the channel list of the external portal. Furthermore i plugged the mag to an adapter that displays power consumption and it's clear that there is no difference between standby mode and deep mode (consumption is around 14 watts for each state). I tried in the options to change hdmi event to enabled or disabled and tried the state modes deep and standby but it changes nothing to the mag behavior. I hope this issue will be corrected in a future revision of the firmware... Thanks
