Some iCloud Data Isn't Syncing

Purchased an iphone 18 pro 9/20/26. Set up with no issues aside from "Find My" was showing "Address Unavailable" for my family. Reading through some Apple forums suggested to toggle on/off wi-fi, cellular, and then signed in and out of icloud. When signed back in received a error "Some icloud data isn't syncing" when attempting to resume syncing it eventually leads to a propr to delete icloud data which icluded my 9.3GB of saved messges for work. It kept asking to sent a code to a trusted device as well. I have an apple watch and it wouldn't send to it. So it was suggested to restart my watch. My watch is now also stuck in a loop as it reset and will not pair to my iphone even though it shows in my trusted devides on my iphone but does not show in my devices under "find my". Apple remoted into my iphone and sent scans to engineering and have been give a 3 business day response time since Monday. Any suggestions on a fix for this or has anyone run into this. I cannot afford to loose the saved messages I have.
