I was just using the Mobile App last night before bed. This morning I get the following message:

LOGIN ERROR
A YoWorld account is required to use
this companion app. Please visit
YoWorld on Facebook.

I have swiped the app off my phone to refresh, turned off my phone completely, but still get this error message. Coincidentally, Facebook also required me to login to my account this morning, even though I did not logout last night. So I'm logged into YW on my computer, using the YW Desktop App, and I've also tried loading YW on Facebook but get a blank page. What's going on?
