No Rehearsal room shown and musicans not in invite list

I created a new rehearsal room, but it is not shown in list of running. None is shown. When I click invite my fellow musicians a not in the list of available musicians. My own name is not listet either. The echo room test was successful. In the commutity list we are shown.
What can I do?

Hi @GypsySwing, at the moment, for your fellow musicians to appear in the list, they need to have an active beta-tester subscription. They need to go here and ask for it: nuapp
