Circle Home Plus and Orbi RBR850 / AX6000

Further update on this as yesterday (4th March), the day after I originally posted, I checked and so far so good:

• Devices wired directly into the RBR850 worked without issues.
• Devices using WiFi connecting to the RBR850 worked without issues.
• Devices wired directly into the RBS850 worked without issues.
• Devices using WiFi connecting to the RBS850 worked without issues.

I decided to go ahead and change the channel used by the 2.4Ghz and 5Ghz WiFi bands and again everything continued to work.  Then later on in the day the same issue arose where devices connected to the RBR850 over WiFi could no longer access the internet.  Around the same time the Orbi app started issuing Netgear Armour notifications about devices joining the network.  After some testing sure enough the same thing:

• Devices wired directly into the RBR850 worked without issues.
• Devices using WiFi connecting to the RBR850 could not access the internet (unless they were put into unmanaged).
• Devices wired directly into the RBS850 worked without issues.
• Devices using WiFi connecting to the RBS850 worked without issues.

I used the Orbi app and confirmed that the Netgear Amour trial had been activated, hence the notifications about devices joining the network, and as before using Compatibility Mode on Circle Home Plus got things working (although limited to 100Mbps download).

Last night I discovered how to disable Netgear Armour, which isn't as obvious as it seems since the Secuity button in the main Orbi app just takes you to the Armour details.  You have to access the Settings Menu, Security, and then there is a toggle to turn it off.

When I had deactivated Netgear Armour I was able to turn off Compatibility Mode on Circle Home Plus and still have a fully working system:

• Devices wired directly into the RBR850 work without issues.
• Devices using WiFi connecting to the RBR850 work without issues.
• Devices wired directly into the RBS850 work without issues.
• Devices using WiFi connecting to the RBS850 work without issues.

This morning (5th March) things are still working correctly so hopefully it is Netgear Armour that causes the incompatibility with Circle Home Plus.  Perhaps others that have had issues can confirm this too.  I'll post again if further issues are encountered and also in a few days if everything continues to work.
