Why, oh why is there no system approved themes.
You cannot use themes and still use colour palette. You either use themes or use colour palette
Themes should be listed as those that work with colour palette, especially as you can pay real money to our hade these themes without knowing if you can apply colour palette to them
If you instal the default theme, and seperate wallpaper n icons (twice the money) you can work around this.... But not always.
It's wrong.
I have told you about this before the oneui updates.
