I am unable to add a banner to a shield.

I have a brand new, never before used shield, along with a being new, never before used red banner. I have searched the web for about 15 minutes trying to find the crafting recipe to put them together, and I got two that worked for the user. So I tried both, and neither one worked. I have tried every possible recipe to combine them, and nothing works. I also went into a creative world and it wouldn't work there. Both times, I was in the plains biome if that effects it. I am on PS4 edition that I downloaded from the PS4 store.
