App always sends spam messages.

The reason for receiving garbage is that non-hair elements use shared home channels. According to the information of Pacific Computer Network, this problem occurs because some non-criminals use the channel of sharing families to attach spam to the text of the sharing notice and publish it to AppleID in batches, and there is no way to stop it. Only by turning off the family function will they not receive this kind of SMS harassment. For users who can't use this function, you can temporarily turn it off and wait for Apple's official repair.
