Did you update your Apple ID, or did you log in with an entirely different Apple ID.
If you updated the Apple ID, you may need to sign out on your iPhone and iPad and sign back in.
If you created an entirely new Apple ID it would not be automatically change on other devices since the new ID would have no connection with the old ID. Again, you would need to actually sign out and sign back in with the new ID on your iPad and iPhone.
