What do you mean, the text message stepped on the content and forwarded it back?

The message is forwarded back after stepping on the published content, which is the icon that the other party cancels stepping. According to the query information, it shows that this is the iMessage quick reply function of Apple devices above iOS 10. The user sent a short message, and the other party clicked a stamped icon, so the user received the stamped message, and the other party canceled the stamped icon, and the user received the stamped message again, probably because the other party was curious to test this function.
