Why is the Facebook Login button in English?

Gilles Van Eylen -

If you have chosen to activate the Facebook Login in your Qualifio campaign, it is important to note that this button detects automatically the language that the participant selected in his/her own Facebook account.

Therefore, if the participant is not connected to his/her Facebook account while playing to a Qualifio campaign, it will not be possible to detect his/her language. The button will be displayed by default in English.
