Your account is eligible to participate in Twitch Drops'.
So can I still get the rewards?
You don't need Twitch Prime in order to be eligible. Twitch Prime Drops is just what Twitch would like us to call it.
If it says you're not eligible then you should try unlinking / relinking. If that doesn't work then contact [email protected] and they'll try their best to help.
