@kuangjichen Ah, I get it, the wix path wix:v1/etc… does not give you an external URL to hand over to a third party, right? You will have to do some translations for the url. I posted about this one a long time ago, about a real https-path for images. But it must be out of date by now (it’s still somewhere on here). Could you give me the Wix-URL to the PDF you are struggling with?
