Old Whatsapp app expired, was forced to use this new Whatsapp messenger app, even if I had backup made, could not restore it or export. Lost all my chat history because of this new app. Always did my best to keep all my history when transfer phone to phone, even when transfering from iOS to Android back and forward and now Whatsapp failed and destroid my 10 years of effort to keep the chat history. I will uninstall this app the moment i have a chance.
