I've had a Roamio Plus with a Mini for about a year. That Roamio Plus#1 got XOD one morning several months ago and so did the Mini.
I just bought a new Roamio plus and moved the Mini to Roamio#2 as the host. There is no XOD app showing on either the Roamio#2 and it has disappeared from the Mini. Any idea how long before the XOD shows up? Everything else is working perfectly
Edited to add: Nevermind. Found out elsewhere that it takes 24 to 72 hours. Maybe this will help someone else
