Sandbox Account Login Problem. "TESTUSER_mrmarman" was working before...
I successfully used "TESTUSER_mrmarman" account of mine before. Nowadays login screen says "Oops, that's not a match."
I logon with EBAY default sandbox accounts like "esandbox10539" but I want to attach a paypal account to my account.
Please activate "TESTUSER_mrmarman" if possible.
Sincerely yours.
