iMessages not in sync between Mac and iPhone on Catalina
Thanks much for any ideas anyone has!
Symptoms
If somebody sends me aN SMS text message, I received it on my iPhone, but do not receive it on my Mac iMessages app.
If I send an SMS from my iPhone, I do not see a copy of it on my Mac iMessages app.
If I send an SMS from my Mac to an iPhone/Mac user, I do not see a copy of it on my iPhone but when the person replies I do see the message in iMessages on my Mac.
Problem Start
This used to work. It stopped worked exactly after I logged out of my AppleID on my Mac (running Sierra) and iPhone and logged back in.
I upgraded my Mac Catalina, and my iPhone to 13.5.1 hoping it would solve this problem and it still doesn't work.
What I've Done
I checked my settings as described below and I tried logging out of my AppleIDs on both devices, doing a hard shutdown, rebooting, and logging into the AppleIDs again on both devices.
On my Mac, iMessages preferences, "Enable Messages in iCloud" is checked and I've tried clicking sync now.
On my iPhone, settings/iMessages is enabled and "Messages" is enabled in iCloud settings.
