Android nightmode/darkmode makes app unusable

This morning, while trying to sync my new work machine to my Keybase account, I logged into the Keybase Android app. I keep my phone on dark mode to conserve battery power. The Keybase app showed white text on a while background, making the app unusable in dark mode.

Reproduce the Keybase Android app's login and sync flow with Android dark mode enabled, especially while connecting a new work machine. Inspect the Android app's dark-mode handling around the affected screens. Done means the app remains readable and usable in dark mode, with no white-text-on-white-background presentation.
