Why are the number of text messages sent at home and at school different? Why can't I get news from home-school communication?

The communication between home and school in my daughter's school is very humanized. Different from ordinary home-school communication products, it is just a short message platform for teachers to release messages to parents. "Green Net Doll" home-school communication: 1) Original registration and authentication mechanism, automatically gathering parents and teachers; 2) "Website+SMS" dual platform to promote two-way communication between parents and teachers; 3) Create a new mode of parent interaction of "Parents' Meeting+Parents' Forum+Parents' Home Page".
