Active MAX subscription, but AI features redirect to payment page

Hello Smart Book Support, I have an active MAX monthly subscription purchased through Apple for $1.99, valid until October 23, 2026. However, AI features have never worked with this subscription. Whenever I select ChatGPT or Claude while reading a book, the app immediately redirects me to the Premium subscription page. I also purchased PRO Lifetime on October 10 for $24.99, but the problem existed before that purchase. I have tried using different accounts, but the issue persists. The app currently shows PRO Lifetime as my current plan instead of recognizing my active MAX subscription. Could you please investigate this issue and restore access to the MAX features I have already paid for? App version: 3.12 Platform: iOS Thank you!
