Reminds me of when someone links to a product on some (non-Amazon) website, I go there, it says "this is the US site, you should go to the [your country] site!", I click OK, and it takes me to the homepage.

With Amazon it's even worse, if you click on an US Amazon product link on an Android device:

My app is set to use Amazon in Germany. I click a link on a page and this opens the app. The app says it needs to switch to US. If I do that, I'm signed out of my German account and end up in an empty US account. I also think that I didn't even land on the product page afterwards. So I had to sign out of that US account and re-sign in into the German account to use the app normally.

So I basically just can't see the link unless I long-press and select open in new tab.

I get this from the Nothing (phone) emails, the direct links in them go to the UK site, but if I let it redirect me to the US site, it's just the homepage. Extremely annoying.

This is also infuriating for all those sites that take to their homepage when you log in instead of taking you back to the page you were viewing.
