The issue is that when you set your phone to dark mode, it messes up the text color. It makes it always white, no matter which of the 4 is selected. This makes many of the bubble colors useless. System dark mode also interferes with the bubble colors. What is shown in the selection vs. what you selected.

Can there be a setting to ignore system dark mode? Or maybe fix this coloring issue? I have Textra set to black on screen color. No matter which I select, the text appears white unless I switch to light mode on my phone.
