When setting an expiry time in Talk conversations, do the old messages get deleted from the database or can they still be retrieved later?
When you manually delete a message, the record gets replaced AND another record gets inserted so the conversation history will show the message indicating that the message was deleted.
When you manually wipe chat history, they get removed from the database.
I also ran a 1 hour auto delete test. The messages were entirely removed from the comments table.
When I say “manually wipe chat history” I mean: click the red button that clears the chat’s history.
