On the Android app, my lists don't sync right at all. I hit refresh but it just goes around for a while then stops with nothing different. (Also, side note, it would be great if there was a progress bar, I mean come on.)
It gives me words that I am studying, but that are really old. I notice that on any day that I just use the Android app I don't learn anything, and I never get any new words, even though my settings are to add words "Fast".
Anyone else have this problem? Really annoying, makes the app unusable for me.
