The ESPN Fantasy Football 2012 app has vanished from the Windows Phone Store and those who have been using the app have seen their teams vanish as well. The app itself has disappeared from the Nokia Collection as well but if you follow this link, you can still find the app's listing.
Unfortunately, the Nokia exclusive is noted (for both Windows Phone 7 and 8) as not being available for your device from your Nokia Lumia Windows Phone. From the online store, the app is simply listed as "not available online" likely due to the Nokia exclusivity.
We reached out to ESPN's Customer Care and received this reply,
"Thank you for bringing this to our attention. We're currently aware of the problem and are working to resolve it as expeditiously as possible. We appreciate your patience and understanding while we resolve this."
Hopefully ESPN will restore order to the fantasy football app as well as everyone's fantasy teams. If we hear of anything new on this, we'll pass it on. In the meantime, you can head over to this WPCentral forum discussion and share your thoughts on the matter.
Thanks, everyone, for the tip!
