Hi there! Yes, the PBS app is supported. You can install it by clicking Home on your remote, then navigate to the search (magnifying glass) icon in the top left corner. From there, type in "PBS" and scroll down to the search results section titled "Apps". If you need more help, please reach out to Samsung Support at: 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat) or Chat with us on Samsung.com: https://www.samsung.com/us/support/contact/
