To preserve conversation history in Enhanced Messaging, we removed the End Conversation menu option from the list view for messaging sessions. Selecting this option prevented future messaging sessions for an end user from being stitched to existing messaging conversation history, which worked against the asynchronous promise of Enhanced Messaging. This menu option is still available in messaging sessions for Enhanced Chat.
Where: This change is available in Enhanced Messaging channels. View required editions.
Note By popular demand, we temporarily reinstated the End Conversation button. Learn
