I contacted EA Help and wanted to update in case others in the same situation find this post. EA Help suggested I could purchase the Sims Medieval deluxe edition through the EA website rather than the EA app. That does appear that it would work--on the website it does show up, whereas on the app it doesn't. There is no option to just buy the expansion though.
I guess I'll keep my eye out for a sale now.
