MacOS 27 failed to send RCS message

After upgrading the MacOS 27 and IOS 27, the message app on Mac failed to send RCS message, receive seems to be fine and iPhone can send message to Android with RCS message. When I tried to send text to Android with RCS on Mac, it said not delivered. It was working before the upgrade and I have tried to toggle text message forwarding but no help.

Try toggling "Text Messaging Forwarding" in the Messages Settings off and back on for all devices: Toggle off, back out of the screen, wait a minute, then toggle back on and you should be good!

I also have this issue and nothing seems to resolve it. I've attempted to disable forwarding, turned off iCloud sync, reactivate it all and nothing just works. MacOS will receive SMS and RCS fine but it will not send. This has been going on for quite a while now which is frustrating because for years it worked without problem.

I have tried that multiple times even waited for more than 30 minutes, no luck.

So sorry! That is what finally worked for me after several tries. Hoping Apple releases a fix soon!
