Why Can't I Include Line Breaks For My Pinterest Posts?
Line breaks can be a great way to edit the flow of information and change the format of your posts.
Pinterest, however, does not allow Pins to be created with line breaks inserted. Therefore, if you are in the Post Editor and attempt this, we will notify you that this is not possible with an error in the top right of the Post Preview like this screenshot:
To resolve the error, simply remove the line breaks from your Post Text.
