Do you support Whatsapp, iMessage, Pinterest link preview or other social platforms?
Basically, Whatsapp and iMessage are using the same social meta tags as Facebook. However, they may have conflict in the link preview image size. Facebook & iMessage prefer to have an image ratio of 1.9:1 width-to-height ratio while Whatsapp requires 1:1, i.e square.
We don't support Pinterest at the moment. Please raise a feature request to let us know your need.
