How so?
In our part of the world that's Meta/WhatsApp.
All school and class related information is shared exclusively via WhatsApp communities.
He needed to verify his identity via an app at pick up time, and needed an gmail/apple account as part of the process. I don't remember which app.
A lot of schools use apps like 'ParentSquare' to interact and manage the student/teacher/parent relationship, and do not offer the same level of communication through traditional channels anymore.
