ROKU doesn't see new server for media libraries but does for OTA Live TV

Server Version#: v.1.42.2.10156-f737b826c
Player Version#: 4.147.1

Windows 10 Pro 64bit.

Today I set up a new Plex server and scanned my libraries.

Problem: Roku Ultra in Living room DOES NOT see the new Plex server media libraries. (It still sees the now non-existent old one) It DOES see the new server for OTA Live tv but that’s the least important thing to me right now.

I have tried: factory resetting the Roku Ultra device and then I signed into the Roku Ultra device with an alternate email account in case it was getting old info from somewhere.

I reset my router and modem. (my ISP helpfully reset my modem with a 4 hour outage today as well.)

Nothing I do seems to get the Roku Ultra to see the new server for both the media libraries and the OTA Live TV signals.

I have a Plex Pass and I have an HDHomeRun networked DVR device.
