New update looks pretty but buggy!

I sadly have to modify my recent review of praise. I love this app for sleeping. Problem is? The latest update is full of bugs. I cannot find anywhere to change the length of time the app plays the ocean waves. It shuts off after 1 hr. It screen does not shutoff after 30 seconds. My iphone stays bright the entire time the app is running draining the battery. The screen needs to dim and then shut off while running, a bright screen keeps my up like a night light. The app details in the App Store shows a rectangle icon in the upper left corner but my app doesnt have that. Is that where the menu is supposed to be perhaps? Finally when opening the app you used to be able o hit the play button and it would remember and play the distant waves that I always listen to. Not any more you have to double click and then reselect the sound you want to hear each and every time. Which app companies would test software updates with a real user before launching updates to catch these bugs.
