If you've not received your Twitter bonus, make sure that you've given it some time. The bonus may take up to an hour to apply to your account.
If the bonus still hasn't arrived, make sure that your Twitter account is set to public. If it's set to private, we won't be able to see your tweet and apply the bonus.
Finally, make sure to be following the prompts from within the app to send your tweet. If you're writing us a custom tweet, it may not be recognized as part of the Twitter bonus.
