Seems incongruous to me - and not good UX - that in apps the delete button is huge whilst the “Done” button is tiny. And it’s at the end of the content flow.
I have to consciously tell myself not to press it!
Can you make it heaps smaller or replace it with an icon, and maybe move it to the bottom of the screen.
This is still an issue for me as well. I suggest either a) switching the Done and Delete or b) Making the delete button smaller and/or RED instead of the theme color
