I cannot register a new sandbox user. I click "register", fill out all of the fields but it gives me the error "An unknown issue has occurred. Contact the website administrator". What sort of error message is this... sort it out.

I have been having the same difficulty as well - is ebay listening?

Same here, looks like this is still not fixed. developer-support@ebay.com can we get some help please?

Hi,
I had the same issue!
It finally worked by adding “TESTUSER_” at the beginning of the Sandbox test username and using a different email and password from my eBay dev account.
Hope this helps!

Running into the same issue atm as well.
Opened a ticket with ebay support to see if they can help.

Had a reply from eBay support via a ticket:
We apologize for the inconvenience, as the sandbox currently does have some deficiencies. We understand this is causing frustration and may be blocking you from testing. So we suggest using production to test if applicable.
Please ensure you adhere to these [best practices|https://www.ebay.com/help/policies/listing-policies/test-listings-policy?id=5039] when testing in production.
We appreciate your understanding and cooperation.

Ran into this just now - you're able to circumvent this by ensuring the name and email are unique.
I'd say eBay's UI should inform you of that, but as we all know, the technology just isn't there yet.
