Your device switching experience is the WORST. You made me lose valuable data without warning, due to a terrible device switching process. When I logged in from my new phone, the app on the old phone immediately cleared itself of all data, without notifying me of the option to back up chats, without a slight warning. There is no way back. This is DUMB, and very inappropriate for a company at your scale. I will try to avoid using WhatsApp for anything important from now on!
