I use my own domain and webspace for my shop. It is a very basic HTML page that embeds the spreadshopy by JavaScript.
When sharing a product to facebook, no image shows up, apparently because the og meta tags are not inserted when the shop is embedded - even though I have explicitly set updateMetadata: true .
I have tried removing any og tags from the html to avoid conflicts, but still they are not created by the JS.
Any ideas why this does not work as expected?
