Just a technical question about lesson usage: are there videos with the courses and I just can't see them (via android smartphone), or is there only text and audio files? I sure hope there's more I for some reason can't see, without, there's just too little explaining and I'd be better off watching Camille's YouTube-clips...! So what do I do wrong?

All lessons are video lessons, with audio as a supplement for some! Have you tried restarting your device and/or viewing on a laptop or desktop instead? I'm not sure why they'd be missing on Android - perhaps try a different internet browser!
