Payments and Subscriptions

I’m a virtuoso piano player and I want to read and play music sheets so I bought the pro subscription for a price. But after a day I bought it, I realized that I can’t reach official scores. To reach official scores, the app needs four times money as a pro subscription, shortly pro plus. I could reach many scores before buying pro subscription but after I bought it, nothing changed. Please change the subscription packs and while giving us sales include the details of the pack. Thank you,
