I had this app installed for a few months and never got any notifications. My wife and kids got sick with COVID, so obviously I had been exposed. There was no way in the app to report my exposure so I called their Help line. The lady was very nice and said she didn't know, so she would call back after she found out. She called back and said they currently aren't tracking this kind of exposure!! So I was out in public and others who were in proximity to me weren't being alerted to an exposure!
