Hey @Snak3_fps,
The tweet just refers to the issue affecting those that had made progress on the event track before updating.
If you updated to version 16.0.3 prior to making progress on the event track, you should be fine. If you haven't yet hopped in-game, please be sure to update before doing so to avoid the issue.
If you had made progress on the event track before updating, you'd fall into the category of those that aren't receiving the rewards properly.
We're working on a fix for those affected, so please keep an eye on the Twitter page for further updates, or we'll provide them in the thread here as well.
