Just to come back and close on this - I’ve now tested from Germany with and without a VPN (VPN end point is in the UK), using exactly the same URL and conditions (open in a browser under the VPN, disconnect the VPN and refresh the browser tab).
So I confirm that it is NewsAPI screwing around with the feed to UK IP addresses, so unfortunately nothing that can be done nor anything wrong with MagicMirror or its modules.
Probably best to mark this as solved, albeit basically crippled for UK users.
