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.
