Sound timing is broken - worst experience ever

I’m simply trying to make a short video with a .wav file as a narration with pictures changing at specific moments in the sound file. It is IMPOSSIBLE! Your product is broken and incredibly frustrating. I click on a specific time of the sound file and it’ll play different parts / times of the file, or if I go back, it will play a separately different part. It doesn’t work, and I can’t time visual transitions based on sound. It’s also incredibly frustrating trying to navigate the layers / timing, I have to zoom all the way out, move the timing bar, zoom in, and even that doesn’t work. Worst experience ever.
