I can see a recent blockchain.info "confirmed" transaction in a shared wallet, but I do not have a balance?
I don't know if you asked this question before or after transaction ae751e14246b4287e44196ec6db01e656872dd7dc3cfb68b44e931a27c431f95 happened. In that transaction, the 1 BTC associated with 15wGmQqaYHhBqB6bEFvrXz4CJGNeBhQkmv is spent, thus there are now no coins associated with it. The balance shouldn't be reflected anywhere because it is zero.
