Hi, I just started the course yesterday and got 22 cards in the repeat stack. Today I wanted to learn again, but the app got stuck after a while in the middle of reviewing. It looked as if it was trying to load a new page, a blank screen with the blue 'work in progress'-circle spinning. When I started the app anew, it surprised me by stating that I had finished Spanish :) Now there are 122 cards in my repeat stack and although I answered most of them correctly, repeatedly, the number is not reducing at all. Please help!
