Where do unopened packs go?

I bought the Big Box 14 pack deal and opened 4-5 of the packs. Before I finished opening the rest I had to do some other things on my phone. When I came back to the game, I couldn't find out how to open the rest of the packs. It doesn't appear that 9-10 packs worth of cards I haven't seen are in my card inventory, but I do see cards from the packs I opened.

How do I see & open my unopened packs?


Once a pack is purchased and the process of opening it has been initiated, if the player exits the process than all cards will be automatically rewarded.
