Circle BROKEN after latest Firmware update

NETGEAR STAFF PLEASE HELP!!!!

Since installing the latest update to version 2.6.2.104, my family started complaining that they had access to the internet.  I quickly noticed that this was only affecting "managed" devices, i.e. those for whom I had an account in Circle with restrictions, all UNMANAGED devices such as my own phone and laptop were unaffected and still have perfect wifi access.  I have tried a number of times to reset circle and get it going again but its not finding it any more and I cannot seem to find a way to fix this, NEITHER can I downgrade or roll back to the previous firmware version.  I have been left with no optoin but to disable circle from the Orbi App rendering my recently renewed £45 a year membership thoroughly worthless.  To say I am pissed off is an understatement.  we suffered this for several days before I found that turning circle off was the only way to give the family access again. In the meantime they were unable to do anything online which given we are still in a pandemic under house arrest was not helpful in the slightest.  

Any and all helpful practical solutions welcomed!!!  

Ps not sure why there is no access to support directly just because the warranty period has expired?  In my view youve released a faulty firmware upgrade and should help resolve the situation?

Thanks
