Not only everybody, but companies, banks and goverment instances are using it too. Some apps that sends their OTP via WhatsApp. Some companies and instances only reachable.via whatsapp bot and whatnot.

I would suggest monster hunter rise and splatoon 3. I found some games are better on the switch with its portability and quick resume feature. Games that has some amount of grinding or 5-10 minutes burst of game play, like the ones I mentioned, works very well.
