Thanks very much for the feedback zomboided. That's exactly what I was looking for.
I got the ovpn files from Nord and it was easy to add them using the wizard.
Everything in your app is working perfectly but the IPlayerWWW app is still throwing a geoblocked error, even though I can connect and play IPlayer content in Firefox on my PC using the same server IP.
I'll try different DNS settings again.
Anyway I'm happy that I'm closer to finding a solution than yesterday....
