When Nano S enters auto-lock with the monero app open and an active (temporary) passphrase set, then after unlocking the device the monero app is still open from the instance with the passphrase.
Only when closing the monero app and then opening it again will the monero app be an instance without the password active.
This behaviour is not consistent with the other wallet apps, in that they will always immediately on unlocking the device fall back to an instance without the password active.
