This is an accepted solution.
I would try manually typing your email in if you're not already. Manually typing the email will ensure there are no additional spaces added to the text box which could result in an error appearing. You could also try using a different browser or Google Chrome Incognito mode to see if that helps. If that doesn't work, then I'd recommend contacting the eBay Sales channel support team for further assistance.
