If I go into Amazon, via Brave, and log-in, Amazon says that I have never placed any orders. Doing exactly the same thing with any other browser, (IE, Edge or Chrome), all my orders for the last decade are visible.
The problem only seems to exist if I use a Desktop Shortcut to Amazon, ie:
When going into Amazon via: Brave -> Google or Bing -> Amazon, then Amazon behaves normally.
Problem solved. My bad. Sorry to have wasted your time.
Please close this call.
