iPhone Name and Photo Sharing not updating for contacts
Hello. I recently updated my contact card poster and photo, however, it is not updating for my contacts on their end. I noticed my mom and my brother still have my old contact profile picture and poster saved and it never updated for them even when I updated it for them on the spot. Everything was set to always share automatically to contacts only. I have Name and Photo sharing enabled but it will never update to my new contact profile picture or poster regardless of what I do. I updated my iphone and they also have their phones updated as well. Could this be an issue on apple end?
iPhone 5s, iOS 12
