that's a nice company, but parent comment had a really important point about depending on Whatsapp for basic social interaction.

most informal social groups, parents included, now communicate mainly on whatsapp. You can naturally say no (i did) but then your kid is left out of most social events unless you're actively syncing with other parents every week to be in the loop (which is what i do and it's excruciating).

Whatsapp as a platform is extremely convenient, which is why other people will have a hard time understanding your reluctance to adhere, it's not uncommon to be seen as eccentric.

so again, congratulations on finding a great company, but there are real issues with the general social dependence on a single invasive platform.
