@timrichards When you go to the Ivory display setting and turn “use system size” on, it doesn’t change when you go to the System settings -> Accessibility -> Display & text size -> Larger text and adjust the size there? I’m not running 27.0 anymore so can’t vouch for that, but it’s working fine here in the current versions.
@ivory No it doesn't change, though it does change when I use Ivory's own inbuilt text size settings. Oddly, changeable system size works fine on ivory on my iPhone.
