Presumably some services have issues with locale? Does anyone run a VPN to home on these devices? I'd never considered taking my Firestick on holiday but I'll definitely consider that for the future.
Correct. Fortunately a number of streaming services are available in many regions nowadays, e.g., Netflix, Apple TV, Disney, HBO Max or whatever it’s called now.
The content may vary between regions though, e.g., you open Netflix in another country and no longer see a show you’re watching while see other ones appear. This can sometimes feel like a feature more than a bug.
