Basic App on your smart phone.

I too had the issue with the line up not loading. I had the previous version and upgraded and it stopped loading. To fix it, delete the app and reinstall it. Its a basic app that is better then the website. The only reason is that you see the line ups like on the display boards at the actual event. It works fine, just a bit slow loading
