I am using a 2016 Macbook Pro running Mojave. On iTunes, the Library, For You, Browse, and Radio sections work just fine. However, clicking the iTunes store results in this:
The Music, Podcasts and Audiobooks tabs give me the same white page, and occasionally the bottom will say "No Items". The Movies and TV Shows tabs give me a black page. I can access the store on Safari, but I can't buy anything without loading iTunes.
I've had this problem for a while now, at least since El Capitan IIRC. It hasn't been fixed after upgrading macOS. Any tips would be appreciated.
