‘The given user is not assigned to this app in the developer portal’

Any suggestions? I get as far as this in trying to set the integration up, then when entering my email get the above message.

Everything is set in the correct way up to this point, and the 'official' Homeconnect integration runs problem free (though it lacks features)

I've managed to work my way past this today only to hit a brick wall (well a blank screen) when I click link account. Any ideas?
