Your SMS texts and iMessages should show up on every connected device, and all your conversations instantly sync up and update. Apple Messages is supposed to be a seamless experience. When things are working perfectly, Apple syncs your conversations across all of them. However, several users tell us that iMessage is not syncing across all devices.
If your iMesssage is not syncing, try these fixes until you resolve the issue: Enable Handoff on your devices. Go to your paired iPhone and open the Watch app. It only works when you sign into iCloud using the same Apple ID on all your devices and computers. Additionally, your devices must have Bluetooth ON and be within BT range of one another around 10 meters or 30 feet.
Requirements Ensure that you have a valid cellular or WiFi data connection. From there, open by tapping Messages app on the home screen to sign in again with your Apple ID to activate iMessage. Complete this process on each iOS device you have. If not, add that same e-mail address on all devices as another. And if no email is listed, add it in. While in this Setting, verify that the Apple ID is indeed correct.
Occasionally, your iPhone Number gets unticked. If your number is not ticked, your Messages App is not connecting to iMessage Servers. This action forces your iPhone to go through the activation process again. It makes perfect that when you delete that message on your iPhone or you Mac, Apple Watch, iPad, etc.
For the Messages app and iMessage, syncing across all devices really means display on all devices. That means all SMS texts and iMessages are sent to all your connected devices and Macs, but there is no current method to detect the deletion of a message and report that back to the system so that all your devices delete messages automatically.
Consequently, you must delete texts from each device or Mac individually. A real time waster! If you notice, there is no iCloud setting for Messages. In a nutshell, iMessages servers copy your messages until a copy delivers to each Apple ID connected device.
And only your devices store all your messages locally, without encryption. But when texts are in transit from one device to another, they are encrypted so that Apple cannot read them. These measures are in place to protect your privacy. Cleaning Our Digital Houses is a Pain! When you send or receive a message, every device shows, and updates those conversations. But then when you delete a conversation, you need to remove each text thread on all devices, one by one and by hand! For a lot of us, all this manual labor is just too much of a pain.
And the only way to clean house is to do through each device, deleting texts one by one. For many, this is a deal breaker. And it makes products like the Apple Watch a heck of a lot less appealing. Well, What Can I Do? So if you are sick and tired of having to delete the same message on each and every device, please let Apple know.
