Are there people who really uses Skype on WP8?

In his blog post Skype's Raul Liive mentioned that in the latest release the app is "Always reachable".

Here is the quote:

"You will now receive Skype calls and 1:1 chat messages even when the app is closed. Incoming call notifications and a Live Tile will notify you of missed conversations. The notifications work even when the device is locked."

Are there people who have actually seen this working? The tile is just sitting there on my Lumia 920 and I never get notifications or calls. Same on my wife's 8x. Am I missing something?
