Slow grading in Duolingo
I've noticed that there is lag in the Duolingo app, upon grading as well as at the point of completion of each lesson. This lag gradually becomes worse each time I redo or proceed to another lesson. Eventually, the app become so sluggish that I have to force close and start it up again.
I'm using the app (version 3.60.1) in an Android emulator called Nox as well as on my Galaxy Note 5. I don't experience such slowdowns on the web version of Duolingo. There is definitely something misconfigured in the Duolingo app that causes this phenomenon.
I get that too on the web version with Firefox , so it's not just you. I close it down and restart and it's fast again.
When the Duolingo app on Android is opened it takes at least one minute to load a lesson. The app is very sluggish now.
