Broken controls bug on Apple phones but not on Web/Android

Hi all, I built this game https://centraldogmagame.com/game/ however we’re running into an issue when the game is played on Apple phones. If you access this game on an Apple phone, this is how you reproduce the problem:

  1. Visit URL, wait for game to load.
  2. Click “Skip Login”
  3. Click “Play, learn the central dogma”

Upon reaching the level select screen, the controls become disabled and buttons are not clickable. On Android phones and in the web browser, the game works as intended. I would really want to see the error messages being produced, but I don’t have an Apple computer to use Safari to debug.

Does anyone know of any potential fixes, or if maybe a recent Phaser update affected functionality on an iPhone? Thank you!
