Battery drain & popups
It's been years and the app still completely hogs your battery. I went from 80% to 40% in less than an hour with the screen on just over half brightness. I'm bumping the rating down until this is fixed. Another annoyance I do not care for: A popup pausing my playback to ask me to turn on notifications. Why? Udemy does not serve a function that merits me handing the app the ability to hog my attention in this way. The stupid learning reminders on the web are bad enough. Leave users the hell alone and let them manage their own time.
