Make sure that your Roku Operating System and app version are up to date. To do this, on your Roku go to Settings > System > System Update and then press the "Check Now" button. Your Roku will update its Roku software and any apps that have an available update. After that restart the device.
For more information, check out this support link: How to update the software on your Roku TV™ or Roku® streaming player
Let us know if there's any difference after.
