Answer 1

I can see yellow cells in a 3x3 grid with a red background. What do you want that's not there?

Answer 2

That sounds like it is a bit of a problem. Sometimes, you might need to wait a while for the code to load. If you have a computer, you can always copy your code and open it with a Web browser.

Answer 3

Ausgrindtube I can't see it with my device... could that be the problem?
