I've noticed that, when navigating to the "Collection" page, the value remains $0, even after cards are added.
I remember being able to see both the number of cards (including the number of unique types) we have, and how much our collections were worth, in Version 1.0, so it seems odd that only the numbers aspect works as intended now.
I'm not really sure if this is a Bug or not, but thought I'd bring it to your attention, just in case.
