Upon further investigation it looks like both Facebook and Google auth on Android are not working—and for different, unrelated reasons. My sincerest apologies.

Upon further investigation it looks like both Facebook and Google auth on Android are not working—and for different, unrelated reasons. My sincerest apologies. It appears the underlying problem is the volume of traffic has tripped something at both of these providers. Google actually works, just incredibly slowly. Facebook says I need to submit the app for developer review—but I did that a while ago and when I go to https://developers.facebook.com https://developers.facebook.com it says I'm all set... I will try to figure out what's going on. If you're interested in the app, please create an account using a password—you'll be able to add Google/Facebook in "Settings" later.
