Happened to me when I saw a book on the US site, I wasn’t able to see all reviews, but there was a button to sort-of “apply” to get approved for seeing all of them.
It took five days, then I got this email.
Interestingly, they’re not doing this on the European site, you can still see all reviews there.
It’s not. I’m in the UK, and ever since brexit (spits) I’ve wanted an EU passport. Pre brexit, I spent several years in European countries, had a home, a job, friends, etc. I’d intended to do it again later in life, and now I can’t. Different countries have varying levels of strictness in what they require, but it’s just not feasible for me.
