Ok, I recieved some pointers on this problem from the community and MS Tech Support, I did everything both sources suggested, still unresolved.
I would like some help from Zenimax or Bethesda.
Problem:
I bought the digital download gold ed of eso from the MS Store. The account I bought it on has everything, but my family on the console gets the core game and the 500 crowns only, the 4 dlc's are not unlocked and the mount and pet are inaccessible.
On a xbox one, all the gamer tags on the console identified as "my home xbox" should have access to everything, completely.
If I buy something through the MS Store or on a physical CD, it should be accessible by all gamertags on that system. The distributed rights and access to all accounts on a home xbox is a great benefit.
So, why can the other accounts access the core game and the crowns from the gold ed, but nothing else?
P.S.
All other titles (CoD, BF, Destiny, Star Trek Online, etc) have no problems being accessible, both in core game and the edition benefits. Even BFs premium membership is distributed.
