You are not alone. There is a thread on a PPLEVIS. Looks like a workaround is to open Amazon in your browser and request a desktop version of the site instead of the mobile version.

Happening on older iOS as well. I suspect a back end issue as trying to open amazon links in dystopia for reddit just ends up with an error that something continually went wrong when loading the content. It tries to load this in the inner app browser. Haven't tried on safari or what not. The website is working fine on PC at least still.

Edit: Checked a link to a Kindle book on Brave for iOS and the page kept trying to load, would get so far then freeze up again and try again. Looks like this isn't just an app issue but something more. Amazon works fine on browsers on Windows just fine but definitely something going wrong with mobile versions of the site.

Yes I’ve experienced this issue since upgrading to iOS 15 don’t know if it’s iOS or the app itself

I'm glad I'm not the only one who has noticed this issue. I have been having to shop using desktop browser.
