In the last software version push notifications worked flawlessly. In the current official release whatsapp and telegram only work when the apps are open in the multitasking view. Hangouts seems to work sometimes, when it's not running/visible. And sometimes something pokes Play Services so that push notifications come through, but everything is really unreliable, which really sucks.

Jolla must realise that a lot of users shoehorn Play onto their devices even though it's a bit naughty - it'd be nice if they had testcases/options in Alien Dalvik to stop the behaviour regressing/varying with every software update!

Maybe they disabled the background connections on purpose for battery usage or something, but I for one would really like an option to allow them, waste a bit of battery and keep push notifications working, as they're a big part of what makes quite a few Android apps useful.
