imessage not syncing across 4 devices
I have a MacBook Pro, an iPhone X, a fifth generation iPad and an iWatch 5. I am using the same Apple ID on all devices. I find I get all the messages on all of the devices but when I go to delete a message I have to do it on all four devices separately. I have handoff checked and all of my operating systems are up-to-date. I have searched on the web and all the various discussions about iMessage and tried all of them. Any new suggestions would me welcome.
