Hmm... When I pulled up one of my Glitch projects on my iPhone Xs the browser-based editor works but the editor view is either cut off on the right in portrait mode or almost offscreen when the keyboard displays in landscape mode. I suspect you can get a better coding experience by connecting your Glitch account to Github and then using an editor that works well on your device. The PWA part of Glitch is completely under your control.
