I attend the Niles church and got the app hoping to be able to sign in for attendance and follow the service notes online. However, I can never get the app to open up properly while at church. I either get a blank screen, or see the home page but none of the links will work. As soon as I leave the church premises, it works just fine! I don't know if this is a quirk of only the Niles campus, or if this problem occurs at other locations, too.
