Can't purchase Realm of Magic

I can't purchase the new Game Pack, TS4: Realm of Magic. In fact, I can't even find it on Origin. Usually the game releases at midnight on the release date, so I waited until midnight as per usual, and I still don't even see it on Origin's desktop app. So after closing the program and reopening it a few times, I decided to see if it was even available for purchase yet by searching for it on Google. It brought me to ea.com and gave me the option to "Buy Now." After clicking this option, it redirected me to buy TS4 Deluxe edition.

I see people on twitch playing the game, so it looks like it's available. Is the game just not out yet? Is anyone else having this issue?
