Scrolling works fine on my iPhone (11). However no keyboard pops up when going to an editor pane. I can move the cursor about though.

Editing is not a feature yet, even on desktop. That's why your virtual keyboard doesn't appear.

Basically the same experience as any Monaco editor on my phone. I’ve recently tried to do quick code experiments on my phone while taking a break on a variety of platforms... basically none are usable. Maybe you were expecting something to be comparable to an existing experience? If so please share.

Code Mirror 6 is supposed to be focusing on mobile-first usability: https://codemirror.net/6/ The creator just had a talk at Fosdem a couple days ago too: https://fosdem.org/2021/schedule/event/codemirror/

I am super excited about a usable mobile code editing experience, and am really surprised how much monaco has languished and failed to deliver here.
