Changing font on iOS only changes the interface font

Obsidian Mobile version: v1.3.0 on iOS

When i change the font (Appearance-Text Font) it only changes the font of the menus and title bar (which I thought would have been the job of the Interface font setting). I cant seem to change the editor font at all.

I have the minimal theme settings plug in installed which also has a font setting, but charging this also doesn’t impact the font.

Please can someone help?

Thanks
