The merchants associated with an app are not publicly available. You must be logged in as the developer to see that information. I suspect this is the issue, you can check the debugging console in your browser to confirm this. Check the network calls and you should see a 401 for the accounts call.
Hello @David Marginian, I don't see a 401 response. This is what I've got (see attached)
Any ideas of what could be the cause of this issue
@David Marginian I am logged in with an account that has "Admin" rights, is that not sufficient?
As I mentioned earlier, you need to make sure you are logged in as the developer. The developer has access to the app and therefore the associated merchants.
