I am trying to set up a Merchant Integration Platform; however, every time I try to set it up in the sandbox, I am sent to www.mip.sandbox.com where it has a "Get Started". I click that and I am immediately redirected back to the same page with this error message "Oops, something went wrong. Please try again." Has anyone had any luck getting this to work or any information on how long this feature will be untestable? Should I just try to set up my project with the older LMS?
