@Pagnmickie Sorry to hear about this issue! When you mean manually do you mean you used a key or you turned Sesame by hand? Sometimes if Sesame's position does not exactly match the "lock" position, the app will consider Sesame unlocked. There's a couple ways to solve this issue depending on the cause; one is to set the Sesame lock and unlock angles using the key to lock and unlock your door, and the second is to use foam inserts inside Sesame so Sesame can better reflect the angle of the thumb turn.
If the issue persists after following the tips above, it'd be really helpful if you can send a video (or a link to a video if over 20MB) to email@example.com so we can take a look and see what's causing this. Thanks! - CANDY HOUSE
