Youtube app notifications not working

Hi guys!

I have a problem with YouTube app. I would love to get notifications when channels I subscribe upload a new video but they just don't work.

My smartphone is: Samsung Galaxy Grand Neo Plus I9060 Dual Sim
Android version: 4.2.2
YouTube app version: 10.08.53

YouTube app settings - Notifications are enabled
Android Settings>Apps>All>YouTube - Notifications are enabled
youtube.com/subscription_manager - "send me updates" boxes are checked

I also tried to delete all the app updates (I can't remove app complately) and install them again but it didn't help.

I have no idea what the hell is wrong.

Help please
