sports app not working

The sports app has ALWAYS been buggy (hit or miss), particularly on weekends when there are lots of games and score updates. But for at least a couple weeks now, the sports app hardly works at all. I get the three blinking dots, then either an error message or blank screen where the app should be. Also, quite often the app just freezes up for several minutes and you can't do anything. Restarting the box does nothing to resolve the problem. It is just a terrible app and as I mentioned, it rarely works as it should in my experience.
