"KEEP MY CURRENT VIEW" choice should be enacted for all updates

Hey Apple: There are a large portion of us that use an iphone as a business tool. Every time y'all have an update you change the way things look, how they act, and try to make them more appealing. And that's great for people who LOVE technology and iphones. To me, that wastes my time and I have it set the way I like. I hate transparency, I hate a dark background, and I hate having to waste my time trying to get my old settings restored. COULD YOU PLEASE GIVE AN OPTION WHETHER TO ENACT THESE NEW CHANGES?!?!?! Just a switch that allows me to choose "keep the current view" would solve my problem. Now my messages have a dark background and I'm wasting my time trying to make the background light again. And no, I don't have a dark view selected. Please include "KEEP THE CURRENT VIEW" as one of your options.
