When it comes to translating "Appeals are currently unavailable" i hesitate between using the word "Appels" or "Recours" for appeals, both mean appeal but Appels is used in the context of law when appealing to a highier court (as in to appeal a sentence in front of supreme court) wheras Recours is used to describe the actual process of it
I feel like either or would fit in the context of a ban appeal, any other french speaker correct me if i picked the wrong one. (ré)examens could be used too.
