@msfjarvis While trying this in the emulator with API level 27, I noticed that tapping Settings on the first onboarding screen (the one with the Let's go button) triggers the following crash:

java.lang.RuntimeException: Unable to start activity ComponentInfo{dev.msfjarvis.aps.debug/dev.msfjarvis.aps.ui.settings.SettingsActivity}: java.lang.IllegalStateException: Setting the checked value before the preference was attached isn't supported. Consider using `defaultValue` instead.
