If you encounter an issue while using the PBS app on LG TV and force closing the app does not fix the issue, you can try reinstalling the app to clear the app's data from your TV and start with a fresh install.
To uninstall the PBS app on your LG TV, return to the LG TV's home screen using the home button on your remote.
In the APPS row on your home screen, use your remote to navigate to the far right end of this row until you see the Edit App List icon and select it.
Use your remote to navigate to the PBS icon in this row. While highlighting the PBS app icon, you'll see a smaller trash can icon appear above it. Use your remote to navigate up to this trash can icon and select it. Next, confirm you would like to delete the PBS app. Once you confirm, the PBS app will be deleted from your LG TV.
You can then try reinstalling the PBS app by following the steps in our help article linked here.
