Looks great...I'm hesitant about the a11y label, but the rest was mostly just questions/suggestions.

I'm still wondering whether Menu, button would be better because you're already on a screen called Manage your pledge where you navigated by tapping Manage button 😄

Cool, this works and makes it properly relocate when rotating the device 👍
