Hi is there anyway to purchase a replacement charging case for my apple AirPods Pro? I’ve looked all over for it for two days now I’ve come to the conclusion that it’s long gone so i need to purchase a new charging case but I read apple has discontinued manufacturing these. Any alternatives or solutions?
