This item is still under review. No new updates at this time.
The end user should be able to export or "save as" chat sessions to a file in a platform neutral format. That would quickly enable other use cases including backup/ export / print / etc.
The option to “discard” suggested contacts in your chat list is rolling out to users. We will be making further changes to make suggested contacts more relevant for new users in the future as well, so marking as partially completed. Thanks for your patience with this one.
