Was that you in the video? You need to spray the outside of the PPF and the inside thoroughly. You're probably right you didn't put enough soap or solution on the inside, but there's no way to tell. You clearly did not put enough soap solution on the outside. And, you didn't press nearly hard enough. You've got to thoroughly spray the outside and squeegee! You're not patting or wiping the PPF gently. The solution lets the squeegee glide, so that you can press hard to get the bubbles out. You are pressing maybe 10% as hard as you need to. And, if you squeegee the outside of the PPF dry, then you spray more, until you've squeezed the bubbles out on the inside.
