I'm having a very hard time taking advantage of this feature. When I click on the link at the top of the website, I get this tiny box that looks like a facebook messenger window docked at the bottom right of the screen containing a wall of text. If I click the button to pop it out to its own window, the situation improves a little, but it's still a huge wall of text.
It would be nice if these messages showed up in a traditional email-style inbox. This facebook messenger-esque style of UI just doesn't work for this feature, in my opinion. Having all messages show up in-line makes it extremely hard to read for me. Call me old-fashioned, but I think an email inbox style of tracking messages back & forth with the teacher would be a HUGE improvement.
If I can't find a way to better take advantage of this feature, I probably won't continue to be a Premium+ member (opting for a simpler program instead). The most disappointing part of the current UI is that Yuki seems like a great guy that I'd like to interact with more. I could really use the help planning out my studies too.
I rarely use the Innovative Language App currently, but I'm planning to use it in the near future when I have more time for actively engaging with the lessons. At the moment, I don't see any way to interact with My Teacher in the App. This would also be a nice way to leverage Premium+ membership.
