Spell Chess: Jumping

    I was playing my first spell chess game. I had gotten all the way to the end of the game, and found a beautiful tactic to win. However, I wasn't able to jump in order to capture the king on e2. Could anyone tell whether it was because there was a certain rule that didn't allow me to jump, or I just didn't know how to do it. I hope that in the future, chess.com makes this much more intuitive. Here's the game: https://www.chess.com/variants/spell-chess/game/59052284/33/3.

Opening your game and trying to capture the king using a jumping potion works as intended.
Assuming you knew how to use it, which is by first clicking the potion of jumping, then the piece you wish to jump over, I could see it being a disconnection issue

Ok, thank you guys!
