I think this option is something that every player disables.
At some point I turned it on but the notifications are so mostly useless as all the important parts, like donation or league about to end is always deleted when the granny has new offers. Absolutely useless.
I think it would be great if we could choose what we want a notification for.
Personally I only need
Donation, pro league Ticket (most important).
But giving us options is a big improvement and would make this Feature a lot more useful.
