XR500 VPN Service not working

Dear all,

XR500 firmware version V2.3.2.114. 

I can see many posts here without a solution regarding the functionality failure of the VPN Service feature in the XR500.

With WiFi off, I've tried using both OpenVPN Connect and OpenVPN for Android on my OnePlus 8T and a Samsung A70 via the mobile network but get the same result on both devices - Successfully connected but cannot browse my home network. 

When home and connected to WiFi - no issues, I can browse my home network.

Have tried all combinations of TCP/UDP, Auto/Internet + home network/home network only.

When using VPN service on my previous router (Fritzbox 7390) it just worked - no issues. 

Following the XR500 user guide steps to the letter - no success.

Tried troubleshooting suggestion of disabling QoS - no success.

How is it that Netgear hasn't rectified this problem since so many have encountered it!?

If anyone in the community has a solution I'd be very grateful if you would share.  My immediate solution = time for a new router.

Exasperatedly yours,
