We are happy to announce that the New Conversation Button has started to roll to the general public, and should be rolled out 100% over the next week or so. We will share another update as soon as one is available.
Thank you for your continued feedback. As many people have pointed out, this is available on mobile today. Support for replying to a specific message is on the backlog for desktop. I’ll let you know when we have progress to share. Thanks.
The team has begun working on this feature. We’ll update as we have more details to share.
