Google Messages adds on-the-fly group sharing for multi-recipient messages
Google Messages is testing a new sharing flow that lets you send a message or photo to multiple contacts more easily by choosing 'Send to a group' or 'Send separately' and creating a group on the fly; if the recipients are already in a chat, it opens that chat instead. The feature appears in server-side tests and isn't widely available yet, as Google continues to migrate users from Samsung Messages.
