Slightly Confused but Excited to try it – Sentry Private Texting & Calls Review

Not sure whats going on but after I downloaded the app l would tap on it and show the blue shield on my entire screen, then it would immediately close the app. It looked like a good app and worked well from the description and the reviews, so I was excited to give it a try. However its a little hard to use the app if l can't even open it
