Problem with the Commander Lilith and the fight for Sanctuary DLC (Xbox One)

I bought the dlc on the Microsoft store and I tried downloading it and it said in my game management page that it wasn’t installed after already installed it. So, I went to the actual Borderlands game management and it wasn’t listed as a add-on to the game. Is there any ideas on how to troubleshoot this?

Which version of the game do you have? I know it definitely does not work on a physical 360, but does work with the Handsome Collection version of BL2 on XB1. I’m not sure about the backwards compatible version of the game though - I’d have to dig back through the forum threads to find out.
