Hello mick719 and welcome to Apple Support Communities. It appears you are having some difficulty loading content in a specific app.
First check the App Store to see if there is an update for the app. If there is no update or f an update does not solve the issue, consider deleting the app and reinstalling it.

If you are still not able to access the app as expected after re-installing, you'll want to work directly with the app developers on a solution.
