Dont know about OP, but in my place, India, Whatsapp is lifeline of society. Wedding invites, sales pamphlets, news, wishes, purchases, money transfer, book sales, car rentals, friends to friends money transfer, progress reports, school communication to parents, 100s of types of clubs, almost everything gets sorted on Whatsapp. The activity which gets limited by Whatsapp (like members in group, need bot etc) moves to Telegram.
