Caldwell attorney David Fischer asks Harmon questions about when the unsent message policy was put into place and Harmon is unsure, he thinks it went into effect around 2018 but the policy itself is beyond the scope. He's just dealing with records at Facebook.
Fischer seemed shocked that Harmon wouldn't know this and after pressing Harmon unsuccessfully for a minute, he calls for a sidebar. After a moment with the husher on, he comes back up to ask Harmon again but meeting another seeming dead end, he asks for another sidebar.
Now after the 2nd sidebar, Fischer asks Harmon: when one unsends or deletes a thread off FB messenger, FB doesn't notify you (with a push notification) that you're deleting a record from our company?
Harmon: No.
