I thought reign of Superman was already out why isn’t on this app
It comes out the same day as blue ray does, the 29th
Two more days for it on the service. As for why it did not arrive with the digital release, maybe licensing deals or some other reason.
As mentioned, Reign of Superman releases to the DC Universe service January 29, 2019.
