@83211688 Ha! Now I try it again and it's there! When I tried before there wasn't a top bar. This is why I tried pulling down, to see if one appeared. I couldn't even get into the Advanced theme settings until I'd selected a primary font colour. And now I've changed it, I can't reset it to the default. It's ok as I've chosen white, but shouldn't we be allowed to revert a single item to the default? 

 @015046e9 In the theme editor, to revert to a default color, you could tap and hold a custom color option then select Remove.
