I’m using an iPhone. I’m updating the word list that I created on the website, but it doesn’t sync on the iOS device.
Sadly, the apps don’t automatically update the courses’ content. To do this, you’ll have to either log off and back on again or (what I usually do nowadays) download the course for offline use (you’ll have to have a subscription for that). Note that, if you already downloaded the course, you’ll have to remove the download first.
I’m doing the same. But this is a permanent solution.
Is that meant as a question? If that’s the case: I don’t know! But as there is a bunch of things that would need to be fixed (see i. e. the Android Bugs thread) I doubt that this one would be anywhere near the top priority.
