iOS 15 Update - iMessages not syncing

I updated both my iPhone 11 and iPad Air to iOS 15 this past weekend. Now iMessage will not sync between the two devises. I have done literally EVERYTHING suggested to resolve the problem... Turning off/on iMessages and FaceTime then rebooting (did this a million times) and I even reset my iPad. Still not syncing. Handoff is toggled on both devises. Send/Receive on iPad shows two email addresses but not my phone number (greyed out.) Is next step to completely erase and start from scratch or is this a know glitch?

Hello BeaWhy,


Thank you for using Apple Support Communities. Based on your post, your messages aren't syncing between your iPhone 11 and iPad Air. We'll do our best to assist.


Are you using Messages in iCloud?

Are you signed in to the same Apple ID and iCloud account on both devices?

Resource: Use Messages in iCloud


You mentioned your phone number is greyed out. Have you set up text message forwarding? See: How to forward SMS/MMS text messages from your iPhone to your iPad, iPod touch or Mac or Add or remove your phone number in Messages or FaceTime


Are other Handoff features working, as expected? For example, if you open a new tab in Safari does it show up on the other device?


Hoping to hear back, take care.

If you are experiencing difficulties with message synchronisation between your iPad and iPhone - on your iPhone:

Settings > Text Message Forwarding - explicitly disable each device for which forwarding is enabled.


Force restart both your iPhone and iPad. After both devices have been restarted, re-enable Text Message Forwarding on the iPhone.
