Estuary themes are still greyed out for Android

it was moved to Colors (just under theme), if you change that the theme will change if it doesnt change the background colour also update to the latest nightly.

Themes are available in Windows version. I use the Curial theme, I want to use that as well in Android but themes are greyed out. Colors are different and Curial is not in there.

only Curial is missing, but you can use the other options and its the same as changing theme.
