School newsletter can't receive some teachers' short messages, how to solve it!

Step 1: Ask the teacher to help you see if you are "closed" or something on the teacher's school newsletter page.

Step 2: If you don't contact 10086 for negotiation. If it is open, please check whether your number is wrong on the page.

Basically, it is the problem that appears in these links. I hope I can help you. Because I often encounter these problems.
