Hi there! I'm Evgeny from the RallyUp team. It looks like isRegistrationModeEnabled parameter not working anymore when creating an event (Enter Greenroom button is not seen).
Expected that when isRegistrationModeEnabled=false - organizers users should be able to enter the Greenroom (Enter Greenroom button should be visible).
For now, I was able to enter the Greenroom only after updating the event with isRegistrationModeEnabled = true and entering the hostPasscode.
