Hi, I have the very same problem. I can log in to my Flying blue account in Chrome and Firefox on my Mac, but I am not able to do it in Safari on either my Mac or iPhone, and therefore I am not able to log in to Air France app.

After filling in the credentials and tapping on Log in button, nothings happen. I have the latest macOS and iOs.
