When a LIFF app was added to a channel, the permission to retrieve the user's email address was revoked if it had been granted to the channel. Please check if the email permission has been revoked or not from the LINE Developers console. Request the permission again if it has been revoked.
We will continue to improve the quality of the services we provide to our developers and we greatly appreciate your understanding.
