Same in mine, but instead of WhatsApp it is Rakuten Viber, which is massively popular in Eastern Europe. Beats me why, I don't like it that much and don't have a slightest idea about what are they doing with our data. But it became an issue trying to communicate without it. I'm a WhatsApp user from the early days, and I'm still dreaming about a day WhatsApp will be "independent" again.
