We identified an issue with the Twitch Drops for the 2/27 Livestream where the notification on Twitch wasn't being sent correctly.
We resolved the issue with the services connecting to each other and this week's and future Twitch Drops should work as expected.
For those that hit the requirements for the livestream on 2/27, you WILL have a Twitch Drop in your in-game inventory when you get the game, HOWEVER the pack will not appear in your Twitch Drops Inventory on your Twitch profile page. We had to flush all pending notifications that were stuck as part of fixing the issue.
If your account was linked correctly and you watched the 2/27 Livestream, you will be getting your Twitch Drop in-game.
