New - RBR850/RBS850 Firmware Version 4.6.9.11 Released

There is definitely something odd going on with Guest Networks with this firmware.

I don't use Guest Network and never have. But I noticed that following a reboot, the Orbi's Guest Network would show up on the list of available networks for 5-10 minutes before disabling itself again.

Then I had an internet outage that lasted an hour or so. For some reason this caused the Orbi (in AP mode) to turn on the Guest Network and this time it didn't turn off. The only way to disable it was to go into the Guest Network section of the control panel and re-apply the settings which disabled it again.

The worst thing about all of this is that it uses whatever details you have set up for the Guest Network in the control panel - which, if you've never used it, defaults to an unsecured network. I've now changed this to secured but it's not a great situation with regard to security for those that don't use this feature.
