Ultimate Evil Edition No Longer Playable Or Installable Xbox

I’ve owned Diablo 3 Ultimate Evil Edition since day one on Xbox.
Every other season I would put the disc in and Install it from the store.

Recently I went to Install it to play season 27.
to my surprise Xbox has removed the ability to install the game for physical copy owners.
its no longer sold separately ???

What is this ? How does blizzard allow Xbox to do this it basically forcing me to buy Diablo 2 resurrected which I already own plus i own the Necromancer dlc already.

So i can no longer play Diablo 3.

Please get Blizzard to contact Xbox to fix this shameful act.
