PROBLEM: No YouTube/Google+ Notifications

[Muertos666]

So recently I downloaded a few apps for my Android tablet. I wanted to be notified by sound when something goes on with my emails, Facebook, PSN or YouTube/Google+. I've assigned custom notifications for each individual site (Zedge has all the sound effects, while MegaSound assigns them)... they mostly work fine, except it seems no matter what I do, I cannot get YouTube working. I know that YouTube notifications actually come from Google+, and I've ticked "get notifications" in the settings in there, and told it exactly what notification I want. From the "Settings" in my tablet, I've gone into "Apps" and into both YouTube and Google+, the "show notifications" button is ticked. I have no idea what else I'm missing, and why still nothing happens. Any ideas?

Just to add to my post, I don't think it is helped by the fact that the Notifications Tab on my YouTube app just WILL NOT work... things do happen, but they never ever show.
