[2021] For those of you asking why you don't have celebration edition content after purchasing the epic games copy...

According to EA support, it will take a bit for all of the Celebration Edition content to appear. They said within the next 48 hours. I am in the same boat as you. I own the standard edition on Origin, but upgraded with Epic Games. After during some research, this is what I concluded. If I get any more news I'll update this thread.

Edit 1: Thread on Answers HQ. Should get EAs attention soon for an official response. Here's the link.

Edit 2: For those asking for my original source, it isn't great but it's all we have to go off of for now. This guy deserves more love

Edit 3: EA has given a response on Answers HQ
