Same here. In the UK. Updated the game yesterday (28th). Logged in multiple times yesterday and today but haven't had a popup about this at all. Don't use mods etc.
This is pathetic. EA release a statement about how they're "sorry" and are fixing the multitude of bugs in the game only to immediately introduce yet another bug with a time-limited reward system that is inaccessible despite following the "conditions".
Funny isn't it how this always seems to happen, but the shopping cart no one asked for was working perfectly from day one.
