Received Whitelist status from Twitter but posts still capped

We run the site lextweet.com, a community of legal professionals using Twitter. It's running on twitter account for lextweeter.com. We applied for and were whitelisted last week. Your message:

“lextweeter: Thanks for requesting to be on Twitter’s API whitelist. We’ve approved your request!

You should find any rate limits no longer apply to authenticated requests made by lextweeter.

We’ve also whitelisted the following IP addresses:

This change should take effect within the next 48 hours.

Thanks much, and good luck with your application!”

However the account appears to be capped at about 30 updates per hour. Can we please receive whitelist status?

Thanks and keep up the good work.
