Yeah, welcome to Denmark. Use Facebook and Messenger or count yourself as disconnected and ootl.
Want to use something a little more private/secure? Some people might use Whatsapp, which most definitely is not another Meta app! ^/s^

PS. Why is the "English" language not allowed in world@quokk.au? What language does the comm prefer?
