Kotlin aside, what is the deal with many websites not letting me zoom on mobile? (It is hard to see what is going on in the notebooks without zooming in.)
I find that annoying as well. Luckily on Firefox Android at least that can be fixed with a browser setting (Settings > Accessibility > Always enable zoom).
I do the same on Safari on iPhone. Enable the accessibility setting and browsers can't lock your zoom anymore.
Thanks! I didn't know that setting existed and I always wanted this behavior.
IIRC this used to be propagated back in the early HTML5 days. At least that's how it got to my personal website. I might've got it from html5boilerplate.com or a similar site.
In Firefox mobile go to accessibility settings and turn on zoom on all websites.
