I have an very good storage Idea for IF.
When you choose an new livery to fly with and tap on fly you are downloading it to your device but we can’t delete the livery
So I have an idea that in settings it is an page in general there it says Liveries and if you tap on it you will see all the Liveries you have flown with and it is an trash curve on the Right side and then you can delete it so you get better storage.
