SMS text sync issue and iMessages in iCloud "syncing paused"

I believe I’m having a similar (and new) issue, a group SMS chat seemed to update just fine on my MBPro but not on my iOS devices. Restarts didn’t work, manually pressing “sync” in the various device’s Preferences didn’t work and I was about to do the sign in and out of iMessages until I had an idea. On the working MBPro thread I typed “Test”. Within seconds the “Test” appeared on both my “stuck” iPad and iPhone, and the rest of the messages sync’d immediately and all seems good (for now). FWIW they’re all on my home wifi network. Maybe try a variation of this on your devices and see if it “bumps them into sync” like mine did?

I have been having very similar issues for several months now. I have a Mac mini M2, iPhone 13 and iPad Pro 4th Gen. My Mac does not stay in sync with green or blue messages some days. It is random. I AM USING the only id I use for log in and I power the devices down daily to try and resolve. It has grown much worse in the past 24 hours though. I deleted about 20 message conversations on my phone last night. My Mac had been staying in sync for several days, but then things went a bit haywire. I noticed my Mac message app seemed to scroll occasionally in the corner of my eye. After a couple times, I clicked it and picked up my phone to see if they were in sync. They were not. Then I scrolled down on my Mac app. The message conversations I had deleted were still on my Mac; HOWEVER, there were message conversations that were deleted long ago that started appearing. It sounds similar to the deleted photos reappearing in the photo Appa couple weeks ago. I've done all the steps several times and when I hit Sync Now on my Mac; it appears to be syncing as it states for 2-3 minutes. Then nothing changes. It is now keeping current on texts for today, but it's not deleting the old conversations which is very concerning.

My Mac has conversations from 2016 to 2022 at the bottom of the list! These were deleted months back or even further. My iOS devices are fine and show nothing older than 2022 which was my cut off point when I was cleaning my iPhone messages 2 nights ago. My Mac app has 26 conversations (I deleted 2 so was 28) with various dates from 4/15/2016 to 9/7/2022 as the last message date showing. This isn't funny as my photo app has now had a picture pop up from a very old deleted conversations that was shared in the text several years ago.

Same thing happening with me. iMessages are syncing, but SMS messages are not. I tried all the steps above, including restarting both after changes, and sign out/sign in from iCloud from the phone app. macOS Sonoma 14.2.1 and IOS 17.2.1

I'm having the same problem. It just started a couple of days ago. iMessages are synching on my MacBook Pro but SMS messages are not. I also cannot send or reply to SMS messages on my MacBook Pro Message app. Does anyone know how to fix this? Thanks! 😃

Same thing is happening to me: iMessages are updating just fine, but SMS messages stopped working in the middle of the day today. I tried all the trouble shooting suggestions but none of them resolved the issue on my Mac. IPhone is working fine.

Same. But not just when an SMS is within a group text. I have iMessage only messages that don't sync across devices. Been a problem for a couple months at least. Have also noticed my Notes not syncing. Google seems to have it down. My Google apps sync almost immediately.

I"m having the same issue as well. iMessages (ie messages from other apple users) are syncing fine, but SMS text messages are not syncing to my MacBook. Just started a few days ago - it was working fine before this.

Oh well. Next day, same issues. I tried.

I had it working for a couple weeks last month, and now syncing stopped working again.
