Question
Cannot Change Page Size after Select Custom
The format of my File is 4x6".
But when the file open with Adobe Acrobat Reader DC, it automatically shows on a page 8.5x11".
I want it show automatically full page by 4x6" instead of 8.5x11", so I go by File|Print|Properties|Page Setup|Page Size|Custom [Name Fixed], trying to change my default page size.
It shows like the below screenshot, my custom option is fixed, I cannot change.
Please help to figure this out.
