Push notifications only when connected to Wifi

[RFreund]

I have a Nokia Lumia 920 and just updated to windows 8.1. It seems as though I only receive push notifications for Skype (among others i.e. viber, facebook, etc) when I am connected to wifi. I imagine this is something to do with the Data Sense but I don't see a setting that would be preventing my phone from downloading the skype messages. Any thoughts on this?

Thanks!
