SAP Mobile Cards - Micro App Booster error

I've been trying to use the "Build a Micro App for SAP Mobile Cards" booster in SAP BTP without success.

During step 2, when I enter my subaccount and space the service is detected as uninitialized, despite the initialization has already been done from the Mobile Service cockpit. When I proceed with clicking on the Initialize Mobile Card button, I receive the error message "No organization exists".

About the environment: I'm on a productive global account where I created a demo CF subaccount with my corporate identity provider installed. I've performed the activities described in this tutorial, and was able activate the service/register the client without any issues.

Am I missing something?
