Warzone Req Bundle

So I’m having a bit of a weird experience. I have a copy of the game, my friend also has a copy of the game, separate Xbones. Earlier today my friend tried to buy it and it said “Sorry you are not eligible.”

A few minutes later on my xbox, i then bought it, just fine. Then a few hours later my friend looked at his req store, and it is just no longer there. What’s going on there?
