Rooms Live funktioniert nicht

Create a Room - and invite people to join you for a live video chat!  ROOMS Live shows you great videos while waiting for people to join the Room.  If you connect with people through a group iMessage - now you can connect with them through a live video group iMessage.  ROOMS Live allows users to hold live video calls with up to five people.  This is just the beginning of an exciting new live video platform that will grow and grow - so if you’ve got feedback or features you’d love to see we’d love to hear about them.  You can even continue to text your friends and family while having a group video chat.  ROOMS Live is convenient and can be launched right from iMessage.  Create a Room for a work project - or a school project - or for your besties - or for your frat brothers - or for your actual brothers.  The people who you invited will be pinged with a notification when someone who’s invited enters the room.  Starting a Room is as easy as starting a group chat.  And if you're enjoying the video, you can keep watching with your Roommates.  Best of all your Rooms are private, meaning you are in control of who gets to come in.  Name a Room and come back to it at any time.  You can do it full screen - or down in the iMessage window.  You can even watch videos with your friends during the call.  If you're not on WiFi, your mobile data rates may apply.
