Ebay Business URL not working

Greetings,
I was recently giving your plugin a test run, but was stuck at the step where I have to input my “eBay business URL” – it kept saying that it was not a valid eBay page.

I tried inputting my seller profile link, my eBay store link, my product page link, and my eBay feedback page link.

All links gave me the same error.

How can I resolve this?

Best Regards,
Julio Lopez
