Anyone else have trouble with using this course on mobile?

Yes, I have the same issue, which means it's impossible to complete the lesson (lesson 3 for me). I took a screenshot of two examples: https://photos.app.goo.gl/qwiBP9FuG6YtGS6w9
I eventually got around it (moving on to next lesson) by "testing out" by clicking the key. Otherwise I could not advance in the course.
I have this same one! I wasn't able to get past Letters 3 Level 0/5 Lesson 1 because it wouldn't let me match dū. Finally tried it on browser and seems to work fine with that though.
