The problem is when our corporate enterprise users attempt to promote tweets in our environment we noticed the “Get Started” button is missing. After doing a little investigation I found that the html to render that content is simply not being returned from Twitter. The minute the user goes off corporate network the content is returned and they are able to promote tweets.
We use Squid on the backend to proxy all traffic and do some filtering. Is it possible we are tripping some security measure and Twitter is refusing to render the promote tweet content?
