None of my live tiles are updating anymore. They used to be and uninstalled and reinstalled, soft reset and power off and on to no avail. Will a full reset fix this? Was trying to avoid having to do so.
Basically it's most likely too many background agents running. (Some apps can have agents running and you may not see them in the 'background tasks' settings screen) I'd advise opening all your apps and checking their respective settings to disable Live Tiles, and other background agent/tasks there on top of blocking unwanted apps in the background tasks settings. Also keep a count of how many apps have background tasks running. More than 15 seems to be the spot where people start having troubles. Good luck.
