Premiere Pro showed an ad video instead of the Start screen
I experienced an extraordinarily long delay today when I started Premiere Pro. The Start screen did not appear and I thought something was wrong with the software, but the menus were still working. After a long delay, a badly made video with no border, title bar, or controls started playing in the middle of the screen. When I clicked on it to see if I could make it stop I discovered that this was done intentionally by Adobe.
I'm paying for this software to do actual work. I do not want to watch someone else's video before I can use my software, especially if it makes the software extremely slow to start up.
How can this intentionally added bug be permanently disabled? It never should have been added in the first place.
