3.020 update needed Roon reboot

I updated today to 3.020 (Pi 3B+Pi2AES+PiTouch) and on reboot, the screen complained that the zone was not found. Tried various steps such as reentering configuration, saving, and rebooting, but it still would not work. Roon would not find the endpoint, either. Eventually, rebooted my Roon Core and everything is working again. Looks something is off in the negotiation between Roon and Ropieee 3.020 when Ropieee spins up.
