A:Answer Hi HBOMaxQuestion, the HBO Max app is available from TV's built-in App Store. If you are experiencing issues using the app, you may want to make sure that you are running the latest firmware version, check your network connection, or try using the Device Car feature by going to Settings > Support > Device Care. Should you need further assistance, please reach out to Samsung Support at: 1-800-SAMSUNG (Available 8AM - 12AM EST, 7 days a week), LiveChat, or Email: https://www.samsung.com/us/support/#contact_us_for_support ^Val
