App Crashes while using it for Baby Monitor

Hello! New guy here and hoping someone can answer a question. My wife uses the app to monitor our baby while she is sleeping. Lately my wife is saying that the app is crashing on a normal basis during the night and goes back to the home screen. We are using iPhone X (iOS 11.4.1), Wyze camera V2, and app version 1.4.56.
Thanks in advance!

 

I believe the issue of shutting down after a couple hours is being fixed in a firmware update soon. Stand by.
