It seems to me anything that requires background processing on WP8 doesn't work with any degree of reliability. Skype is one exampe. I can't receive calls or messages unless the app is in the foreground. This makes it a useless communications app. The Lync client is the same way. And these are both Microsoft products (well Skype sort of is).

Other apps, such as Amazing Weather HD also don't seem to function in the background at all. Even though it is enabled in the system settings and in the app settings. It only updates the live tile after launching the app in the foreground. Many other live tiles seem to just stay stale as well.

Even soc media notifications in the ME tile aren't always live. Sometimes they are and sometime they're not.

It seems to be a bit hit and miss on my 920 whether tiles update or not and whether I receive notifications as well. I've now got used to doing manual checks rather than relying on any form of automatic notifications.
