We are using an iframe to allow the user to re-authenticate without leaving our SPA, which worked well with the old authorisation page, but the 2FA shows blank with the following error:
Refused to display ‘https://[our-domain].eu.auth0.com/u/login?state=g6Fo2SBrUlE0bzNCSFZDZWpHRDhvSW9xZndnNENlVlB5TGhkeKN0aWTZIFRQOTJsNlJCQWRoSkVCV3BKcS1sYlpJcHJTMnptRk5yo2NpZNkgcjdWVm8zNHdiakxDZTQ1bDJacFA5Y0lyQURMazNkZ0I’ in a frame because an ancestor violates the following Content Security Policy directive: “frame-ancestors ‘none’”.
