When using seed vault, you need to set the default wallet to nothing and disable shields on the website where the adater will be used. If you do not change the default wallet, seed vault will not be found. And if you do not disable shields, when you select mobile wallet (seed vault), only a darkened overlay will be displayed, without an interface for interacting with the wallet.
