iPhone 6 Plus issues with app

Hi, I have a iPhone 6 Plus and I have been having issues ever since the last apple iOS update. Of the 3 cameras I have I can only see 1. Sometimes all 3 will work and a next time only 2 or 1. My wife have a iPhone 7 Plus and she have no issues whatsoever. Please check and fix please. Thanks
