Watched 3.25 Announcement but no Twitch drop

Can you first please try unlinking your Path of Exile account from Twitch from the Manage Connections page and then relinking to Twitch? You can access the Manage Connections page here?

You may also wish to double check your Twitch settings here to see if this refreshes your entitlements.

If that doesn't help we would be happy to check into things further. Please contact our team at support@grindinggear.com so that we can look further into it with you if this is the case!
