Problem with syncing Messages - be grateful for suggestions!
iPhone 16Pro using iOS 27.0 and iMac 2021 running Tahoe 26.6.2
Messages on my iPhone and iMac are not syncing correctly - there are messages on iPhone that are not on iMac and vice versa.
I've tried several fixes - turning off Messages on iPhone and restarting; syncing my iCloud account; checking mobile number and email addresses are correct in messages etc.
But even after this I can see recent messages on one which are not appearing in Messages on the other.
I recently updated to iOS 26.6 and 27.0 and its seems to date from then?
TIA
