Hi,
I created a japanese course using the web aplication, but when I tried to see it in my phone i just see random characters. But in the web version is showing ok.
And an existing course: Minna no Nihongo II (all Lessons 26-50) Is also showing with random characters, but this course Minna no Nihongo I is working ok (in android)
I have a Samsung S5 and just updated the memrise app.
