Printful just emailed to say that from March 15, 2023, unless we grant additional permissions on Shopify, they won’t be able to receive or fulfill orders. They have an ‘Enable Permission’ button on their app page, but when I click it, it takes me to a Shopify error page that reads ‘Oauth error invalid_request: The redirect_uri is not whitelisted’.
Has anyone else encountered this issue and found a solution?
