Udemy has a lot of great courses but your app is the worst I have seen. I can't imagine an app so bad I took the time to review. I download the videos to watch later but it keeps loading to play the video, I have to restart the app each time. I minimize and come back and it starts playing from an old video, it forgets videos that I have completed and lots of other issues. I am using this app on a good 2021 phone with 8gb of ram so it is definitely not the phone. Please you guys can do better.
