Messages between Mac & iPhone not syncing after upgrade to MacOS Sonoma 14.4 & iOS 17.4

The syncing process between MacBook Air (M2 2022 / MacOS 14.4) and iphone Pro Max 15 iOS 17.4 is broken. Everything worked fine and after the upgrade some messages are synced and some not. I have to different sets of messages (iMessages & SMS) on MacBook & iPhone. I tried to remove all messages and switching sync in the cloud off and then back on but id does not help.


It seems like if iPhone & Mac are near each other and are on - the messages are is sync, but when I'm away and send/receive few messages on iPhone they stay on iPhone and does not sync to Mac and vice versa.


Any ideas for help? I called Apple support but they were unable to help.



MacBook Air, macOS 14.4

In my case ExpressVPN on my Mac seems to be the issue. When express VPN is on, my Mac doesn't get SMSs from my iPhone even after forcing a sync. Turn VPN off and force a sync and the missing messages are synced. Running Mac OS 15.0.1 and iOS 18.0.1
