Have been learning Danish using the Duolingo app for over 2years. Have a 837 day streak and have, up til now, enjoyed my daily learning. Recent changes to the app are, however, spoiling my learning experience. The opportunity to consolidate newly learned aspects of the language has been vastly reduced and the ability to revise chosen sections is no longer as easily accessible. I cannot understand why these changes have been made as they have been nothing but detrimental to the learning experience.
