My husband has his iphone 6s and ipad set with the same apple id. I feel like some of the imessages are not coming through to the ipad. I have researched and checked all settings and feel they are correct. I see messages from me and a few people but I feel he is texting more than what is coming across. If he were to delete imessages from his iphone would it then automatically delete them messages off of the ipad? I know that he can delete his safari browser history and it deletes it from the ipad so I was thinking the same would happen with the imessages.
