I'm switching to Linux right now and I haven't really looked into replacements for each piece of software. Used Paint.net for at least 10 years, tried Gimp first but didn't like it. What do you use?

I am using Android 15 and App version 1.1.4.1 (151).

I changed the custom theme colour to various animals, and also changed to custom. Neither appeared to have an impact.

Selecting anything in here results in no changes here to put it another way.
