Anyone else have trouble with using this course on mobile?
It gets stuck and says that my answers are wrong when there are two more options on the "tag the correct pairs" section.
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.
