I have been emailing Jetpack's Support staff and they are relying on your plugin for their post short URL's. Now for over a week I have tried shutting off my theme and deactivating my plugin's but have had no success.
The latest belief is that WP-Bitly isn't updated for WordPress 3.8.1 for this feature. I was wondering is an update is rolling out soon. If anything can you guys contact wordpress's Jetpack support for more details?
