Automatically change server to preferred server type on Kissanime
Automatically changes the anime player every time you go to watch an episode. Just choose your favorite player and the script will save it for you. KissAnime already enables this if you have an account, so try that first. This script is more useful for people who don't want to make an account for whatever reason.
Is the page changing back to your previous default server constantly? Change the linesetTimeout(() => {hijackServerSelection();}, 2000); so that the delay is longer. Your internet connection is probably causing delays that are preventing the script from working properly.
