Orbi app not connecting to the router with ios 14 upgrade (RBR750)

Hi

I have had a similar but different issue after upgrading iPhone x and iPad Pro to IOS 14. My Orbi Wifi has been operating without issue for nearly 2 years with up to 20 different devices attaching (other IOS devices, Apple TV's, Smart TV's, Sonos etc). All device upgrades including IOS have completed within this 2 years and no impact on the reliability of the Orbi WiFi. However I upgraded both my iPhone x and iPad Pro same evening about 4 weeks ago and since then whenever I attach either my iPhone or iPad (with IOS 14) to the Orbi WiFi it freezes/stops the WiFi for everything, thats including other IOS (V13) devices smart TV's etc., the only way to restart the WiFi is take IOS14 devices off the wifi and reboot the Orbi router, then so long as I leave iPhone x and iPad Pro off the Orbi wifi then no issue it works away. 

As the iPhone x stops the Wifi when it attaches I cannot use the Orbi app but I do have the option to allow access 'Local Network'. So instead I use the https://orbilogin.com and can connect to Orbi router. I have updated the firmware, done a factory reset, installed as new (as few times) and still same issue, IOS 14 devices causes the Wifi to freeze. I have never installed Orbi Nighthawk as an App.

I am totally frustrated and while I did contact Apple and they did escalate they clearly identify the problem as the Orbi router issue. 

Anyone had a similar issue and at this stage before I throw the Netgear equipment into the trash I would try anything.
