Problem


I have a problem for a while now with the board when I have to solve a problem I can see only one piece on the board, whatever what lesson it is, I can skip lesson as many times I want and still the same trouble doesn`t lets me continue to solve new problems, i thought that maybe some day it will be fixed, but unfortunately didn`t happened till now and I am waiting for about almost one year I guess so... What could be the trouble, I`ve tryed even from my phone or from other computer and it`s still the same... What could be the trouble that doesn`t allow me to see all the pieces from the board?
You must have an Apple. You need a PC.
//I assume you are making a joke. The screenshot you included was one of the super-basic lessons that shows you how pieces move. It was the lesson that shows how bishops move. There was only supposed to be one piece visible.
