If you live in the US, going on vacation to Europe doesn't affect how much salary you get paid or what language you speak, but it does impact the content you are allowed to watch.
Yes, that’s true if you only move within the EU. Has been the case for a few years now, also with other streaming services, due to new EU portability laws.
It's so silly. They could at least make it clear - I forgot about it on holiday in Canada, watched a couple of episodes of a series (enough to get into it), returned home to the UK and it wasn't there. I didn't realise until then that would happen; I hadn't even remembered that it was a possibility.
