Opening Warzone REQ pack during loading screen

While waiting for a matchmaking game to load, I clicked to open one of the new Warzone REQ packs I purchased. While it said “Processing”, the game loaded and went into a match without ever opening the pack. After the match ended, I went back and checked to open the pack but it was no longer there. Does this mean I lost the pack now or did it credit to my account without me ever being able to see what was actually in the pack that I purchased?? Thanks!
