Vero 4k stuck with red light on front of device, wont power on

Hi, I just received my brand new Vero 4K. I’m very happy with it, but it seems to have a similar problem as OP. When I boot it up, it works fine. Then I leave it for a while and when I come back the light has turned red and it won’t turn on until I re-insert the AC. Is there some sort of sleep/shutdown timer I don’t know about?
