Maybe I remembered it wrong, I used "green" in the solution mode, and the production problem-solving mode limited "blue". Maybe I got it wrong, :) Thank you！

Automatic solution is working for me. Solver must draw solution using green color.
******I tried all the colors, only "green" can pass. If one of the colors "red/green/blue" is selected in "problem solving mode", "red/green/blue" should not be selected in "problem solving mode" Are the other two colors okay? I'm a bit confused here.

The penpa link of Numberlink has no automatic answer verification function. What is the reason? Thank you!
