WhatsApp is a messaging app that you can use to communicate with your friends and family. However, if you’re not comfortable using the app on your phone, there are ways to use WhatsApp without having to change your last seen. To start, open WhatsApp and sign in. Then, open the Menu bar and select Settings. On the Settings screen, select General. Under General, select Security and Privacy. Then, under Security and Privacy, select Last Seen. Now, when you send a message or make a call on WhatsApp, your last seen will be automatically updated to reflect what people are talking about in that conversation.
