I am in a similar situation where I can not link a Sandbox account to a developer accounts. What information do I need to provide so you can link them?
@MTS_Justin I do not see my merchant ID / seller ID account on the Sandbox. Can you just link the two via the e-mail address, <removed> please? Both the dev account and sandbox account use that email.
