As far as the Navigator's App, on our Alaskan cruise in August, before one of the shows, Cruise Director Peter suggested that we all restart the app each morning so that it would catch any updates made overnight. Maybe that will help people get correct info? We had no issues with the app with our LG phones. I had my phone on silent and the light would blink if I had a text from the kids. (I LOVED the app for all the search capability--mostly we used it to plan out the next day while waiting for the evening show to start.)
