I don't have screenshots, I don't remember exactly how, but I remember a little bit of it. So how it looked as if there were 2 boards, one shifted to the right of the other. It looked like it was confused on if I started the lesson or not. If I am able to replicate it, I will comment images but right now I don't know but anyways what happened is I finished a lesson, then I went to the next 1 (forgetting that I only have 1 per whatever ammount of time it is.) and it just had a double board, 1 was starting position, the other was probably the first challenge of it. (Idk, this was yesterday that it happened) and it looked quite weird. Again, if I am able to replicate it I will comment an image of it.
Have a great rest of your day!
