When I remove a chat room, I do it this way:
1. remove all the message docs in the chat room,
2. then remove the chat room doc.
>From the definition of the Syn Function, I think this could remove the
message docs and chat room docs on all the related mobiles, right? Is there
any other issue with this way I did not think of?
Thanks for your quick response.
