How to remove 2 second black screen before splash screen?

I've been really struggling with this recent problem where on the start up of my app, their is like a 2 second black screen then my logo shows up. I have the Plus version and I really hope their is a way to make it skip that 2 seconds. Cause, when it was just the Unity Logo on the splash screen, it would load very fast and the game would start perfectly. Thanks for the help!
