How to change the default language of Facebook share page on iPad? Whenever I want to share something on Facebook using another app on iPad, the Facebook login page show in Chineese.
I can change this by choosing English at the bottom of this login page but after I login the following pages would be still in Chineese. 

How can I change the default language?
Did you try to set your default language on Facebook on English (in account parameters) ?
What is the language you use on the iPad and on Facebook right now ?

EDIT : after some tests it's seems that is more Facebook API related (because the problem is on several apps at a time).
Either developers don't call correctly the Facebook login, or it's a bug.
