Old Chats are disappearing from my Chat-Overview in Whatsapp. I did not delete them, and they are still there: When I search for a contact and then click on them, I can see all the messages of the chat, but nevertheless this chat is missing from the Chat-Overview.
Now my problem is: One of my contacts has quit whatsapp over a year ago, so their account is not active anymore. And therefore I do not see them in my contacts-list. If only I could click (or tap) on that contact, then all the messages would be there again, I am quite sure.
But how can I open this chat, which is not visible in the chat-overview anymore and does not have a valid contact attachted to it?
