Ratings and reviews

It's an amazing app. As a beginner, I have been using it for two days. However, it has mistakes that even as a beginner I was able to notice. Some descriptions of the words are exchanged (when it's a phrase) for example: 우리 가촉이에요. It says that the word 우리 (we; uri) is... and talks about the description of the word family. Then says that the word 가촉 (family) and starts talking about uri. Also, sometimes the language is incorrect. An example was in French instead of English. It's a shame, 2 stars.

There's a random pop-up that doesn't show up everytime I click the KSI website part of the app. And it stays there for a long time. It's so annoying. Please fix it.

I have tried downloading this app several times but always get a ' connection to server' error. I've tried it on different wifis and also on data and nothing seems to work.
