Follow this guide to get a RSS scrolling ticker

Open scheduler and insert a new asset. Choose scrolling ticker.

Paste your desired link and follow the setting below. Make sure to set the scroll speed to the lowest to get smoother playback. Hit OK when ready

Right click on the newly created asset and hit preview to see it working.

And with this hopefully it works fine. We used feeds in this example, but be found that the ABC feed does not work for an unknown reason.
