I have ran into a situation with accounts ui unstyled while testing on an ios device. Everything works fine in the app and on the simulator. On the ios device the #login-buttons container is empty where additional dom nodes should be.
The attached screen shot will show what I mean.
Current packages install:
Accounts Ui unstyled
I recently ditched Facebook login from the user accounts package because it was not working properly. I am disappointed to see this is also having issues at the device level as well.
