door lock not manually unlocking when locked using the app

Major Safety Issue---Recently after an update or something I have found that my simplysafe door lock will not unlock from the inside if the lock is closed using the app or the keypad. No matter how much you try the lock will not unlock. This is a MAJOR safety issue. If you lock the door manually then there is no issue with unlocking the door, This only happened I believe after a recent software update. How can I correct this?
