Sync either stuck or not working at all

It seems to me that the sync functionality for Lightroom products is getting worse.  I've had more troubles with syncing in recent releases that is really making it a useless feature and workflow.

My last issue forced me to clear all data which caused me to lose all my synced collections. 

This time, I imported almost 600 pictures into Lightroom Classic on my desktop and then let it sync.  I then went to my laptop and used Lightroom CC and could see the pictures and went throuh and spent a copule of hours picking and rating them. 

When I got back to the desktop, none of the rating tags synced.  Checking sync status, it shows a file from my phone is downloading. There's no other status or anything that indicates it's stuck.  I've deleted that file from my phone but no change. 

I've tried Rebuilding Sync Data and no changes are shown.  

I really don't want to delete all sync data again because I'm going to lose all my sync collections and I'm going to have to rebuild all those collections.

Losing the ability to make changes from multiple devices, or the web, and have them sync across devices removes 90% of the value of my subscription.  Today's bug has cost me several hours of work and I have to go through and re-rate and re-pick through the photos.

In addition to the sync problems with Lightroom CC is stuck syncing over 3600 photos.  

Any clues besides global destruction and rebuild of synced collections?

Currently on version 10.4 build
