MediumRoastSteam I get this on my iPad too. I can live with it if the theme is better for others as the functionality is fine, but it definitely doesn’t look as nice.
If I change to day mode the grey boxes remain, but I can’t read any text other than the title.
My iPad is set to dark mode (i.e. in the iPad global settings) and if I change to light mode the page looks fine, so I guess it’s just a conflict between the system mode and the way the Oxo skin has been designed.
