Thanks, publishing a hotfix now
Edit: should be rolling out once Google approves it. It's an issue with trying to migrate settings (before the migration path was just blow it away and start fresh) since I made a change there. Clearing app data or reinstalling will also fix it if you don't want to want for the hotfix.
Edit2: Should be live now
Edit3: just to keep all the info in one place, issue persists in 1.0.70 so I'm rolling back some of the Settings migration code. Hotfix 1.0.71 is in review with Google.
