I am part of a WhatsApp group with 12 good friends. We’ve had the group for years and use it quite regularly to keep up with news, photos etc. I noticed this morning that one of my friend has changed the settings to disappearing messages. I don’t want our conversations to disappear! I want to politely raise it but wanted to see if IABU? Too sentimental, or is it ok to want to have a record of our chats?
