I've been using the sesame app on my iPhone 6 Plus and now 7 plus and all issues I've had have been addressed and it's really been working great. It's also been really cool to see how far it's evolved. Over the last week I've gone away on 3 different overnight trips and each time I came home I had to open the sesame app and unlock manually. Each time the first time I went out after getting home, it worked perfectly when I came home. I was thinking that maybe I had reset the phone on each trip to cause this problem or maybe there is an amount of time when it stops running in the background. I definitely didn't manually close the app.
Not sure if I'm doing something wrong or this is a bug in the app.
