I am having the exact same problem with the Product Hunt app for iOS that this reviewer has:

The Facebook login doesn't work for me. This happened a week ago, and again today. I've deleted and re-downloaded.

It's the same problem this Twitter user has:

So, my @ProductHunt iOS app login attempt via Facebook just results in an infinite spinner. Any idea how to solve this? Reinstalling is had no effect.
