In order to clear the cache in the Peacock app, you can uninstall the app and then reinstall it. This is for Apple OS users. If you are an Android user, go to ‘Settings,’ tap ‘Apps,’ choose ‘Peacock,’ and tap ‘Storage & Cache.’ Lastly, touch ‘Clear Cache’ and restart the app. If any error persists, tap ‘Clear Storage’ instead of ‘Clear Cache.’
