"Family" (shared) reminders in iOS 13 are not working - how can this be fixed?
My apologies to the AskDifferent community - this was mostly just a rant due to frustration. After updating my iPhone to iOS 13.3 (like the other devices) then resharing the "Family" reminders, they started syncing with my wife's phone. I was just being a bit impatient, then those click-bait articles put me over the edge. :/
