Fiori Mobile Admin Console User Experience Inconsistent

I currently explore the SAP HCP mobile service for SAP Fiori to package my own app as described here.

When I want to add a new app I often can not get past this screen:

The Get Started button is just not clickable, despite only one or even no app currently present in my account. Sometimes there is a reaction but the screen just turns blank, leaving the Mobile Secure frame and menu in place.

If I pass this screen eventually, it asks me to select my Fiori Launchpad. Which is detected as unreachable. What is not true, the Launchpads condition is perfectly fine if I check the URL manually:

This error - again - can be circumvented by trying over and over.

Once I created an app configuration, I might want to remove it. But how? Just click Details/Select Fiori Application(s) again (might not work on first ten tries, see above)? Because the delete button is always grayed out:

I also checked the Mobile Service for Development and Operations. A configuration for each new Fiori Mobile app is created automatically and cannot be deleted.

Sometimes if I open the app configuration I get an error like this (vanishes on next try):

Failed to fetch application setting plugins. Please contact your technical support team for assistance with error token: 57b2ca3bd2818

The packaged app requires a login on startup. But that failed using my old trial account. Using the exact same configuration in a new HCP trial instance worked fine. Is there an official migration path to keep accounts?

I used Chrome as well as Firefox in both private/non-private mode. The results are always the same.

As the whole cockpit still states Mobile Secure, I wonder if it is still in transition and beta overall?
