👎One thing that puts me off doing more lessons is the advertisement that we are forced to watch which takes 30 seconds or more to finish and then, when we think we can go back to the lesson, it takes you to Google play store so that you download it. You try to leave Google play and it takes to another advertisement. It keeps looping 😡 till you shut the Duolingo app and start it all over again. I deleted this app 1 year ago, and I'll do it again soon.
