Jafauske - while not as savvy and thorough as you, I, too, read Matthew's report with hope as my Win10 IdeaPad, Samsung Tablet, and Moto Z Play Droid have not synced consistently for at least a month as I've followed this thread. Yesterday, it stopped completely after a text exchange in the morning. I uninstalled/reintalled, etc. etc. No luck. I'll keep hope alive as I continue to follow smarter people like you....
