interesting to see, that the notifications are still present, even after all the negative feedback they got.
I'm not saying that having notifications is definietly a bad thing, but they way it's handled here is. If we can't use UI elements due to them, than they're more of a hindrance than help to most players.
I'd suggest (as many before me had) a toggle to enable/disable them in the settings menu; or a new implementation of them that doesn't cover as much of the user interface, and most importantly, doesn't cause extra delays to the useage of the game, such as notifications causing people to wait during fights, (what gets exceedingly annoying the more fights someone has in a row) etc.
Also I'd recommend actually checking out the feedback you receive from the community on the forum, so you wouldn't have implemented this abomination of a "feature" to the players on the live server, while it scored nothing but negtive results on the test server as well. Even better, check them out on a separate development server before even putting said feature on the test server, and make sure it doesn't get even to the test server, while it's in such a halfbaked state.
