Love the app but I have one question.... – The Clocks: Alarm, World Clock Review

I love using this app. I am not sure if I am missing something or not. While using the app I am not receiving any phone calls. I hear no alerts for text messages. However, I do get the text message banner notifications. I probably will stop using the app if I can’t figure out how to still hear incoming calls and text messages. Any suggestions would be appreciated because I would hate to give up this app!
