Regular user name changed. My WhatsApp keeps crashing and I have been added into a group with a load of international numbers. I’ve disabled this setting now so only people in my contacts can add me, but I have no idea what’s going on. Is this happening to anyone else? I don’t know how I can secure my account as it’s not as if there’s any sort of password you can put on. Advice welcome, I’m not the best with technology!
