Every time I launch a 5.7 project the NEW tutorial Tab is open. I have to close it then I get a warning “Tutorial Closed“ and I have to acknowledge it to close the warning. This is incredibly frustrating to do every time a launch a project.
So the default option when creating a new project in 5.7 is the “Intro To Unreal” instead of the “Blank”. I would suggest putting this back to blank moving forward.
