Goodreads app on the iPad Mini freezes on Goodreads account log-in screen

Goodreads (version 3.3) on an iPad Mini

Description:

Keep getting an interesting bug with the Goodreads app on my iPad Mini.

Basically, the app gets frozen on a screen that is asks for my preexisting Goodreads account. I cannot back out, I can't access the "Forgot your password?" option, can't select any of the options on the bottom of the screen.

I've had to delete the app and re-download in order to get it working again. Reboot the iPad might, but I don't like doing that.

This bug is much easier to show than to describe, so please see the attached screenshots.

Steps to Reproduce:

1. Download the Goodreads app (version 3.3) on an iPad Mini
2. Dismiss the Updated Book Page pop-up
3. Select "Sign Up"
4. Select "Sign Up with Amazon"
5. Sign into an Amazon account - using "Sign into Amazon" button
6. From the "Do you have a Goodreads account?" prompt, select "Yes"
7. From the "Meet your next favorite book." page, select "Sign In"
8. Dismiss the invalid email address error message

Result: App freezes after an "invalid email address" appears on the "Meet your next favorite book." account sign-in screen

Expected: App should not freeze after the user receives an "invalid email address" error message on the "Meet your next favorite book." screen
