This morning I noticed my WPCentral live tile didn't update. I looked in Background Tasks and the app was mysteriously blocked from running in the background last night. Huh? This has never happened before. In the app update information it said something about a network error. All the other apps I allow to run in the background updated just fine last night and weren't mysteriously blocked. It was just the WPCentral app. Don't know if it's an issue with the app, or if perhaps it has something to do with the latest firmware update for the Nokia Lumia 920. I haven't experienced any of the connectivity issues that other people have been reporting though. My phone has been working just fine. Weird. Hopefully, this was just a one-time glitch. Anyone else experience this?
