Take comfort in the fact you're not alone. Try different grips to help with it.
Also, you can get more over the disc to help with that. Pull the disc across your chest a little higher, too.
Also, you need to pull the disc closer to your chest. It probably feels really close, but if you look at the video (the 2nd shot specifically) you'll see that the disc is about a foot away from your chest and your shoulders are turned away already.
What you need is to have the disc inside the crook of your arm as it passes your right pec, then gets slung out. You'll get more snap.
