Poor experience of the Android app
After an update, the app cannot be lauched easily, and I was force to access Duolingo with web and keep making typos(due to the nature of Chinese script, the course in Chinese cannot accept some kinds of typos).
The performance of the English version Android app is getting down since some day the performance of Chinese version is getting better, but now all becomes very hard to launch, just like several months ago.
Hello, I'm so sorry that you're having this problem. :/. I know it doesn't address the android issue, but I'm wondering if I could help with the typos issue on the web. If you're using the web version on your phone, you may be able to add a Chinese language option to your keyboard that you're using. If you're using a laptop or other device, you can probably also add a Chinese option for your keyboard. I added a Latin America Spanish language option on both my android phone and my iPad.
I hope you'll be able to do the same. I hope this helps a little.
