Have Unity Pro - Builds start by advertising Unity

Unity Engine
1

I am a Unity Pro user yet when I start my games builds, I am informed that the game is powered by Unity in their stock advert. One reason I paid good money for Unity Pro was to remove this irritating feature. Can someone explain if I am doing something wrong (ie I am missing a build setting which will remove their introduction) please.

Are you talking about Andorid / iOS?
Mobile app do all have a start logo / screens , in unity pro you can replace it with your own. (in the players Settings)
On desktop you should not need to anything to get the start screen away.

Edit:

I have resolved the issue in part with your assistance.

Thank you very much.

On Mobile you can just set the splash screen in the player Settings , that will overwrite the default unity splash-screen.
Do you still have a splash screen from unity on desktop?
If yes that should not be if you have the pro version.

I have the logo in desktop builds made with Unity Pro. How can I get rid of it?

Edit: forget it - I found it in Player Settings/Splash Image.
