Hey, with my Warzone Req Bundle, it keeps appearing in the store to be bought but each time i click it it says I already have it purchased and i can now open it. I have been able to open 0 Warzone Req Packs so far and i was curious what is going on. I know a few people weren’t receiving them earlier on but I haven’t seen anything about the Warzone Bundle still showing up as an item to buy after it’s purchased.
Edit: Apparently both my Warzone Req Bundle and my Advance Promotional Req Pack are both stuck at 90% installing and wont complete. Im new to Xbox One and really dont know what to do. Help 
I’m also having issues with the Warzone Req Bundle. I put the code in on xboxlive.com while at work one night and it said there was a problem and to try again. I tried a second time and it went through. Now on my Xbox One when I go into manage the game it shows that it is installed but I can’t find it anywhere in the game and I haven’t received any packs from it yet. Any word from 343 or Microsoft about these issues?
EDIT: Aw crap, I just found out that if you bought any of the editions that came with the Warzone Req Bundle, such as the Collector’s Edition, you can’t buy a second one. The person at Gamestop talked me into buying a second one to get extra items but since you can only have one I can’t get anything out of it and it looks like a waste of $25. Thankfully, I called Gamestop just now and they apologized and offered to take $25 off my next purchase, so in the end no harm. Just be aware you can only have one Warzone Req Bundle!!
I was able to luckily get my downloads to complete but i still havent received the Packs in game yet. The Microsoft Rep i worked with told me that Halo 5 was having DLC issues so its a known issue on their end. Hopefully it’ll be fixed soon.
