The Trigger issue resurfaced with this update. When I used Roon the same day as the update, no music was forth coming. I rebooted and all was well.
Today, again ....no music. And after a reboot, still no music, but I heard a "click" indicating the trigger did something. It probably turned off.
I tried rebooting again, and now it works. Hopefully it will continue after the next time out.
There were a few auto upgrades where the trigger worked, but a lot of these firmware upgrades have the "trigger bug."
