The person in charge of the business can't display the submission failure when sending short messages in groups. Why?

Fifi Softcom platform has a powerful group sending function, so in the process of users submitting short messages, the system will edit the short messages according to the users' content. So as to accurately judge the submitted content. Generally, there are 70 words in a line. If the number of words exceeds, it will be sent through multiple messages. When the user submits a short message, the system will prompt you that the content of the message submitted exceeds the standard length and will be sent twice.
