Chats: Start Facebook Messenger transition and Start Chat button display fixed

We’ve fixed a couple of issues in our Chats apps :hammer_and_wrench:

  1. An issue with transitioning to Facebook Messenger has been resolved. Previously, opening links starting with didn’t open due to Facebook errors. Since we’re waiting for an official response from Facebook, we’ve switched to using links. This change should make it easier for customers to open Facebook Messenger.

  2. We also sorted out the display of the Start Chat button. Before, on certain CMS platforms, the button didn’t take up the full width of the chat window.
