I have uploaded two different versions of the same image using sizes recommended for FB and Insta. I've clicked on "Create variations" so I can insert the size needed for each platform. But when I change the page for FB so that it is the right size, the image for Insta changes to that image too, and therefore doesn't fit. In addition, right now, the FB post looks good in the preview at the right, but it says it isn't the right size. And vice versa for Insta...looks cut off but there's no warning of it being the wrong size. Help! Should I not be relying on the preview to let me know that the post is okay?
