I have the same issue with the Android app, is there an update coming for that? I also find it confusing that when I open the app, even though I've started down Fundamentals 1, it always presents me with the "I'm a Beginner/I'm More Experienced/Songs/Gear and Tone" options. It seems like at this point, I've started down a learning path so it would/should default to my last lesson, progress, next lessons, etc.
Otherwise, great content/videos!
