iMessages not Syncing with Mac

Hi All:

iMessages were working fine between my iPhone 13 Pro (iOS 15.5) and MacBook Pro (macOS 12.4) until sometime between yesterday evening and this morning (no texts in that period--but all texts from today not syncing on my Mac).

I've read multiple threads on this forum. I've turned text message forwarding on and off, logged in and out, restarted both phone and computer, checked to make sure I'm logged in with the same Apple ID on both devices, etc. None of that seems to make a difference.

The situation is that my iPhone is working fine (iWatch also working) but none of the messages are showing up on my Mac.

Thanks for any new ideas!
