I leveled up my chingling to 94lvl and waited for night to go to next level and evolve it but it did not evolve and i tried giving rare candies that also didn't work please help now my chingling is 100lvl it did not evolved i have attached an screenshot of the game so please help me with the loss as soon as possible.

You would have needed to faint then get max happiness to trigger the evolution. Try fainting the chingling then complete a few battles to get it back to max happiness. If this doesn’t work you might have to use a mysterious candy to trigger the evo because already level 100
