Circle on Netgear R8000P

Hi there,

I am having huge problems trying to get Circle working on my R8000P with an Apple iPhone. It seems to work ok for 3 days, then suddenly history stops being tracked and no sites are filtered - so I turn Circle off, uninstall iPhone app and start again. OK for 3 days then stops working. So I upgraded to the premium version for £4.99/month. Exactly the same problem. I called Netgear support, they transferred me to Netgear in the USA, who then transferred me to CIrcle in the USA who promptly cut me off with an automated message saying I should call Netgear support. I raised a Netgear support case and have been told to call a USA number from the UK.

All router firmware and iOS software is current and up to date - can anyone provide help please?
