If you own a Roku 4 model (4400X) and cannot open the PBS app, please see the below information.
Unfortunately, Roku no longer supports Roku 4 models (4400X), and we have no way of updating the PBS app on these models to fix any technical issues that occur.
Since we cannot update the PBS app on your Roku, our only recommendation at this time is to use a newer device still supported by Roku or an alternative streaming device that supports the PBS app.
