Iphone and Ipad Mail Yahoo account inbox.
All the messages contained in my ipad and iphone mail Yahoo account inbox have disappeared and it does not update. All the other folders. draft, sent, junk etc are intact and update. If I go into mail on the imac the inbox is intact and all the messages are there and update. I have tried deleting the account and reinstalling but that has not corrected this. Any help appriciated.
