One of the features of the secure chat history is that messages are displayed as users would have received them.
For example, if an insecure conversation is transitioned to a secure conversation, all previous insecure messages sent
from the opposite party will be displayed as though they were received insecurely in secure mode. Eight participants (47%) clicked on the action items presented in the insecure messages. These past messages seemed to cause a moment’s confusion. However, as soon as the other party started chatting securely, all participants ignored the previous messages and continued with the task.
