Websocket and user with multiple opened connections - broadcast to every connection

I have opened multiple browser tabs, every has subscribed to an identical topic named user:id. When a backend broadcasts something to this topic, only one random browser tab receives this info. Is this proper behaviour? Should I generate additional UUID for that topic name for every browser tab?

if they are all on the same channel they should all get the broadcasted message.

If you post some code/info on setup, maybe we can find the bug.

Sorry, it was my fault. Everything works fine
