To Big Request Header - has been an ongoing issue since 2017.

Deleting cookies, history, cache - does NOT work.   I've tried 3 different web browsers on 3 different computers and nothing, it will not work.  So colour me surprised when I go online to see if there is a fix and I see complaints about this problem ongoing since 2017.    If you cant get your shipped items paged fixed at least give the actual tracking number in your emails because this error prevents anyone who gets it from seeing when their order will arrive.  Its ridiculous - 2017-  absolutely unacceptable.

I agree! This is ridiculous. I would like to track my order.
