is possible to recover unsaved chat session?

Unfortunately, unsaved chats are deleted when the meeting ends. I would recommend enabling the Auto-saving chats option in your web settings. 

Accidents happen and software malfunctions also happen.  A really great feature would include the option for chat histories to be automatically saved for up to 24 hours before being completely deleted from the cloud.  This is especially helpful to individuals who may be Zoom meeting novices and unaware of the need to turn on the feature to allow for meeting chat histories to be automatically saved.

Is this still the case?  Really hoping it isn't.  I thought the save was checked but alas not.
