Why has the language in the app turned to French? I don't know French.

I am on an overseas trip to usa and suddenly the Samsung members app changes it's language to French.

How to switch back?

It's seems not to be a language change, but à country/région change.
You access the french community of samsung members.

Maybe some tips here on how to change your country in your samsung account

Lol. This seems to be a general issue 

Hillarious. Had it for some time now but it started to bug me. 

No we have not put in French or any other language. This is a Samsung bug!!!
