Orbi + Circle Filtering out most URLs

I have recently added a new device to our network and even though it is on an 'Adult' profile with no filters whatsoever - not time limits, nothing, when visiting sites from a google search, it insists that certain sites are filtered.  Either saying the whole category 'Health' or whatever is filtered or just that I've been filtered despite the settings being unfiltered...

I have tried rebooting the rooter, I have cleared cache, I have restarted my phone and my circle app, I have moved the device onto a different 'Adult' profile, I have moved it to an 'Unmanaged' profile, and yet it still says stuff is filterd!! How this can be when the whole profile is 'unmanged' is a mystery!!'

Its absolutely doing my head in. It really feels that each time a new firmware or update is made on Orbi, circle goes into a tailspin and really can't keep up.  As I'm paying a large amount in subscription fees and I say over the last 12 months I've had it, its not worked correctly for at least 40% of the time.  

Would love to wallk away but difficult as I've made a substancial hardware investment...

the Circle firmware version is 2.1.8.9 and the router Firmware version is V2.5.1.22

I need this to work.  As I'm working from home 100% of the time I can't spend half my working day trying to decipher whats going on or having to switch parental controls off completly but then still spend half my day monitoring my kids internet and screen time use... 

Please advise.

Thanks.
