I can verify what JREM is seeing, the game no longer loads, you just an indefinite loading screen. Which is odd because it mostly worked until today (although I was also seeing the profile issue anonanonanon was seeing, where your data kept getting deleted and random profiles kept appearing), and I have it blocked in my firewall so it shouldn't be able to update. It looks like the game was set on a timer to stop working.

Why does the game keep deleting your profile, and adding random ones? It means you can't keep track of calories or which workouts you've done.
