Some users (including this one) see a large, prominent "message" button when visiting the support accounts for brands including Apple, Beats, Uber, Activision and a few others. According to TechCrunch, this isn't rolling out to everyone yet -- it's just a design test.

There's also a new detail included in the profile page that says when the companies are most responsive, a handy thing to know if you're trying to get help quickly. Apple's support account says its most responsive from 5AM to 8PM PT, for example.

We've reached out to Twitter to see if it has any other details on its new profile feature, including when it'll roll out to more support accounts and when more users will start seeing it.
