Ok, I made some progress.
I disconnected my phone from wifi and connected it to the VPN. I then used Fing to ping 1.1.1.1. It worked!
It appears that this is a DNS issue, as trying to connect via domain names does not work. I will mess around with that for a bit to see if I can discover the issue.

Hmmm. dns.google.com and ford.com both ping from my phone over VPN.
I distinctly remember (years ago) discussing OpenVPN with people who wanted to stream videos that were restricted to their home country when they were actually in another country. Not exactly kosher, but better than robbing liquor stores.

I got it working!
I added the following to parameters to the OpenVPN Connect config file:redirect-gateway
dhcp-option DNS 8.8.8.8After re-adding the connection, it now works correctly!

Wow. You found it! My smartphone ovpn file does not contain this, but it works. My guess is there is something different about the OpenVPN Client on our phones. I do not see this as a setting (parameter) and do not see a way to control the level of detail in the OpenVPN log.Internet search for redirect-gateway returns quite a bit of information.
