Failed to create listing: System error. Unable to process your request. Please try again later.

I've spent a lot of time trying to figure this out but haven't had any luck.

I'm trying to send a simple JSON request to create a product listing on eBay's sandbox (UK), but I keep getting this error:
"Failed to create listing: System error. Unable to process your request. Please try again later."

I've waited two days, but the issue is still there. It seems like something is wrong with eBay's service.

Also, when I try to use https://www.sandbox.ebay.co.uk/, most links are broken, and pages don’t load properly.

Has anyone else faced this issue?

Yeah I am facing the same problem. I tried the offical sample of AddItem (https://developer.ebay.com/devzone/xml/docs/reference/ebay/additem.html#Samples) and it also returned error code 10007.
