This used to work fine so I know this is something that is somewhat recent but we have shortlinks for affiliates to use that use isrefer.com but when they are shared, they don’t show the images that are in the og:image tags of the page they redirect to.
The destination page is 100% setup correctly to show the proper image, I’ve tested that thoroughly so I know the issue isn’t my page. When I enter the IS refer URLs into facebook’s debugger, it shows 3 separate IS redirects, which are shown in the image I’ve attached
On a normal redirect URL, the debugger would show the original URL and then the destination url, but this is not so something very weird is going on with the IS redirect
