Ahhhh I see. Yes it has changed when tapping the value and allows those other options.
So if I did the lowest at 20 sat/b, left "Final" unticked, but found it hadn't confirmed in say 2 days. How would I go about bumping it?
In the history tab, select your unconfirmed transactions, you should have an option to see the Details and there should be an option called Bump Fee. Click on it and adjust your fees accordingly.
