A useful feature would be to have an expiring/disappearing messages option on chats. 30 days, 90 days etc. Obviously there's a balance here, but having just logged on after two years away from the app, and then being able to see photos and messages I sent to people, as well as the photos they sent to me from two years ago is troubling.

I was under the impression messages were deleted after 12 months but that cannot be the case.
