So after working so hard on setting up the Community chatrooms, WIX come along and discontinue support, and instead want us to use their new GROUPS app. BUT not sure what's really different.

WIX do this a lot- change things that don't really need changing, or adding features no one really asked for.

All I can see about this change, from Chatroom to Groups, is that Groups was developed in-house rather than by a separate team. But it's still a lot of work for us to move from one app to another!
