I enabled the "mobile services, user" in my Neo Trial account. But as soon as I access the mobile service cockpit I receive a server-side error.

HTTP Status 500 – Internal Server Error
And when I e.g. try to access the mobile cards the screen is nearly empty - offering no actions:

Is this a general issue with the SCP or are mobile cards not supported in the trial accounts? Didn't find any clear information about it.
Thanks.
