It was stable for me but does not have any Parental Control on these beta fw.
My setup is similar to you but I have 4 x XT8's. My ISP provided modem/router does not have modem only mode.
For me, it was stable for 6/7 days and then got this error:

Got this:

And it carried on with similar logs
All the 3 nodes went down and had to be reset. Still on 46061 with uptime 5 days 7 hours. Teams is a lot more stable for me on 46061 than any stable fw after 42095. Not really sure what caused the errors.
