Google Merchant Orders - 414 Error, URL too long to process

Question

Any time there is more than 25 orders in my merchant orders list, and I have to page through to see the next 50, 75, etc, I get a 414 error 'url is too long. that's all we know.' message from Google.

I looked at the URL, which is generated by Google by the way, and it's over 2300 characters long... I know that 2000 is the approximate limit on URLs in terms of characters for most browsers. I contacted Google's support staff and though they were very nice, they were more clueless than I was.

Has anyone else ever encountered this issue?

Thank you!
